What if you could transform your daily shower into an invigorating infrared session without needing a jackhammer? Many people dream of the benefits of a Sunshower but shy away from the thought of a weeks-long bathroom renovation or the risk of damaged tiles. It is perfectly understandable to dread the dust, noise, and uncertainty regarding electrical safety in a wet room, but these concerns are often completely unfounded.

Installing a sunshower in an existing shower is surprisingly simple these days, thanks to smart surface-mounted models specifically designed for this type of situation. This allows you to enjoy direct infrared heat and healthy UV radiation without having to strip the entire bathroom. In this guide, we explain which models fit perfectly in a smaller shower cabin and which technical steps are required for safe installation. You will discover exactly how to achieve this sustainable wellness upgrade for a result that also looks extremely stylish.

What is a sunshower and why is it the perfect upgrade for your bathroom?

Imagine this: you step into the shower and are immediately enveloped by a soothing warmth that penetrates deep into your muscles. That is exactly what a Sunshower does. It is an innovative system that simulates sunlight in your own bathroom. Many people wonder: what exactly is a Sunshower ? At its core, this device combines powerful infrared radiation with a safe, low dose of UV light. As the warm water flows over your shoulders, the technology provides a level of relaxation that you would normally only find in a professional spa.

Installing a sunshower in an existing shower is the ideal way to enrich your daily routine. Instead of a separate, awkward infrared lamp that you have to place somewhere, you opt for seamless integration. It saves space and significantly increases comfort. It is a smart investment in your health that perfectly aligns with Warmteshop's modern vision on bathroom heating. With this, you create an environment where physical well-being and aesthetics go hand in hand.

The power of infrared and UV light combined

Its effectiveness is based on two key pillars for your body. The short-wave infrared light penetrates deep into your skin and muscle tissue. This promotes blood circulation and helps your muscles recover faster after exercising or a long workday. It is a direct form of radiant heat that you feel immediately, which also helps relieve joint pain.

In addition to the benefits of infrared for muscle recovery and pain relief, a specialized treatment for chronic pain or sports injuries at Bowen Therapy Reboot & Restore by Anna Hugill be a valuable addition to your physical recovery process.

In addition, there is UV light. Especially during the dark winter months, we often suffer from a lack of natural sunlight. The Sunshower emits a controlled amount of UV radiation that stimulates your body to produce vitamin D. This strengthens your immune system and gives your energy levels a significant boost. It is a safe way to maintain that healthy vitality all year round, without having to leave the house. Moreover, the synergy between these two forms of light has a positive effect on your mental well-being and your biological clock.

Wellness in your own home without major renovations

Your bathroom is no longer just a place to wash quickly. It has become a personal oasis of tranquility. By considering installing a sunshower in an existing shower, you are choosing a luxurious upgrade that immediately adds value to your home. You do not need a major renovation to embrace this technology. Modern surface-mounted systems make it possible to create that hotel-chic feel even in a compact shower cabin. It fits perfectly with a lifestyle centered on self-care and sustainability, without compromising on your interior design. The result is a low-maintenance solution that contributes to your daily comfort for years to come.

The technical requirements for installing a sunshower in an existing shower

Installing a sunshower in an existing shower is technically feasible, provided you take a number of crucial prerequisites into account. Because you are working in an environment where water and electricity come together, safety always comes first. This is not a project for hasty decisions; proper preparation ensures that you can enjoy the infrared heat worry-free later on. Fortunately, you don't need to be a full-fledged engineer to understand what is required, but a structured approach is essential.

Electricity and safety in the wet room

Strict regulations apply to electrical appliances in the bathroom. These are divided into zones, with the shower cabin itself subject to the strictest requirements. For safe operation, the device must meet the IPX5 standard, which means it is protected against water jets. An essential part of the step-by-step plan for a flawless installation is checking your fuse box. The Sunshower must be connected to a dedicated circuit with a 16A fuse and a 30mA RCD.

The biggest challenge in an existing bathroom is often concealing the cables without removing all the tiles. A smart solution is to run the cables through the back wall of the shower, if possible. If the wall adjoins a bedroom or landing, you can create a small opening there to run the power supply through. This way, your beautiful shower tiles remain intact, and the technical work will be invisible afterwards. For the connection, always use a heat-resistant cable of at least 3 x 2.5 mm².

Measure space and dimensions

Before you definitively plan to install a sunshower in an existing shower, you should grab a measuring tape. There must be sufficient distance between the shower head and the infrared panel to limit direct water jets onto the ventilation openings. A distance of approximately 45 to 60 centimeters is usually recommended. Also pay attention to the mounting height; for the best effect, the center of the panel should hang at approximately shoulder height so that the radiation reaches your entire back or torso.

Don't forget the ventilation. For built-in models, air must be able to circulate behind the unit via special grilles. Are you opting for a surface-mounted model? Then installation is simpler because cooling takes place via the sides of the unit itself. Unsure if your shower cabin is suitable for this wellness upgrade? The specialists at Warmteshop would be happy to review the technical possibilities for your specific situation with you.

• Check if there is a free depth of at least 10 centimeters for built-in models.
• Ensure a smooth wall finish for a watertight mounting of surface-mounted models.
• Check whether the existing wall structure can support the weight of the device.

Recessed or surface-mounted: which mounting method suits your renovation best?

When you decide to purchase a Sunshower , you face an important choice: will you go for a sleek built-in installation or choose the convenience of surface mounting? Both options have their own charm and technical requirements. Installing a Sunshower in an existing shower often requires a solution that respects the current tiles and walls, but that does not mean you have to compromise on style. Technology has advanced to the point where both mounting methods give your bathroom a luxurious look, provided you make the right assessment for your specific situation.

Surface mounting: the ideal choice for existing showers

For most people looking to upgrade their bathroom without a complete renovation, the surface-mounted version is the absolute favorite. The biggest advantage is that no demolition work is required. The unit is mounted directly onto the existing tiles, significantly reducing installation time. You can often enjoy your first warm infrared session within just a few hours. This makes it a very accessible and sustainable solution for those who want to see quick results.

In addition, surface-mounted models offer a smart solution for compact showers. Special corner models are available that make optimal use of the unused space in a corner. As a result, you lose hardly any room to move while showering, while still benefiting from the full wellness experience. Because cooling is provided via the sides with surface-mounted units, you also do not need to mill complicated ventilation ducts into the wall. It is a straightforward and efficient way to immediately bring more comfort into your home.

Flush mounting: for a seamless finish

Although built-in installation is often associated with new construction, it can still be worthwhile during a renovation. This is especially true when working with a false wall or a hollow wall adjacent to another room. By creating a niche, the glass of the panel disappears completely into the wall. This creates an extremely minimalist and sleek look that fits perfectly in a designer bathroom. It appears calm and is also very easy to keep clean.

However, for built-in installation, a watertight finish is of crucial importance. You must pay extra attention to the sealant edges and the connection to the tiles to prevent moisture problems behind the wall. Also, do not forget that a built-in model requires ventilation grilles to dissipate heat from the electronics. Whether you choose built-in or surface-mounted, the effect on your well-being remains the same. It has been scientifically proven that controlled exposure to light has positive effects, with the World Health Organization (WHO) conducting extensive research into the health effects of UV radiation. Installing a sunshower in an existing shower is therefore a conscious choice for a healthier living environment in your own home.

• Choose the top-up option if you want to keep dust and demolition to a minimum.
• Consider recessed installation if you are aiming for a seamless, hotel-chic look and the wall construction allows it.
• Consider corner installation for smaller shower cabins to save valuable space.

Step-by-step plan for a flawless installation of your sunshower

It is time to put theory into practice. Installing a sunshower in an existing shower is a project that requires precision and patience, but with the right preparation, it is perfectly doable for a handy DIYer or a professional. Before you start, it is crucial that you have all the necessary supplies at hand. Think of a good drill, spirit level, screwdrivers, and of course, the right sanitary sealant. Safety comes first, so always ensure that the circuit breaker in the fuse box is completely switched off before touching the first cable.

The first physical step is determining the exact position. Use the template supplied with your Sunshower for this. This template helps you accurately mark the drill holes on the existing tiles. Use a spirit level to check that everything hangs perfectly straight, as a crooked panel not only disrupts the aesthetics but can also make achieving a watertight seal difficult. Installing a Sunshower in an existing shower therefore starts with perfect alignment.

Drilling into existing tile work

Drilling into tiles that have been in place for years can be nerve-wracking. After all, you don't want cracks in your ceramic or natural stone. The golden tip is to use high-quality diamond drill bits. Never start directly on the smooth tile; first, stick a piece of painter's tape on the spot where you are going to drill. This prevents the drill from slipping and causing damage. Drill at a low speed and do not apply too much pressure. As soon as you have drilled through the tile, you can switch to a standard concrete drill bit for the wall behind it.

Use only plugs suitable for damp environments. After the holes have been drilled and the plugs inserted, you can attach the back panel or mounting brackets. When making the electrical connection, ensure that the cables, such as the prescribed 3x 2.5mm² cable, are connected without tension and in accordance with the zone specifications. Do you want to be sure you are making the right choice for your bathroom? Ask the experts at Warmteshop for personal advice for a result that lasts for years.

The finishing touch: waterproofing and testing

Once the unit is securely mounted to the wall, the most important step for the lifespan of your bathroom follows: waterproofing. Apply an even layer of high-quality sanitary sealant along the edges of the panel. This prevents shower water from running behind the unit, which is essential for electrical safety. Smooth the sealant with a sealant stick or your finger for a sleek, professional finish.

Allow the sealant to cure for at least 24 hours before using the shower again. After this waiting period, it is time for the final check. Switch the power back on and test whether both the infrared functions and any UV lighting are working correctly. You will notice that the direct radiant heat immediately provides a sense of luxury and relaxation. It is a sustainable solution that transforms your daily shower into a moment of pure wellness, without having to demolish the entire bathroom.

• Always use painter's tape to prevent slipping on smooth tiles.
• Choose stainless steel screws to avoid corrosion in the wet room.
• Check the sealant edges annually for wear to guarantee watertightness.

Frequently asked questions about the sunshower

Can a sunshower be installed in any existing shower?

Yes, in most cases this is perfectly possible as long as there is sufficient wall space and a power outlet can be installed. Surface-mounted models, in particular, are specifically designed for renovations because they are mounted directly onto the existing tiles. You do need to take into account the minimum distance to the shower head to prevent too much direct water from getting onto the ventilation openings.

How much power does a sunshower consume per session?

An average ten-minute session consumes surprisingly little energy, often less than 0.2 kWh. This amounts to just a few euro cents per session, depending on your current energy tariff. Because the infrared radiation heats your body directly and not the entire bathroom, it is an extremely efficient way to bring wellness into your home without high electricity costs.

Is installing a sunshower dangerous due to water?

No, provided the installation is carried out in accordance with the applicable safety regulations, it is completely safe. Sunshowers are specially developed for use in wet rooms and have an IPX5 certification, which means they are splash-proof. By leaving the installation of a Sunshower in an existing shower to a professional, you guarantee a watertight and safe installation in your bathroom.

Do I need a separate circuit for a sunshower?

Yes, for reliable operation, a dedicated circuit with a 16A fuse and a 30mA RCD is strongly recommended. This prevents overloading of other appliances in the bathroom when you switch on the device. Furthermore, it ensures that the power supply remains stable during your daily infrared session, which benefits the lifespan of the internal electronics.

What is the difference between a sunshower and a regular infrared lamp?

The biggest difference lies in the safe integration and the unique combination of light forms. While a standalone infrared lamp often only provides heat, a Sunshower combines short-wave infrared with a safe, low dose of UV light for vitamin D production. Moreover, the device is specifically designed for the humid environment of the shower, which would be absolutely unsafe with a standard lamp.

Do I need to completely demolish my bathroom for a built-in model?

No, a complete demolition is not necessary, but you do need to be able to create a niche in the wall for the housing. This is often easier to achieve if you have a false wall or if the wall adjoins another room that you can access from the rear. If you prefer not to break into your current tiling at all, then a surface-mounted model is the ideal choice.

Are there special requirements for ventilation with a sunshower?

Yes, adequate ventilation is essential to safely dissipate heat from the internal electronics. With a built-in model, you must install special ventilation grilles so that air can circulate behind the device. With surface-mounted models, this is easier to arrange because cooling takes place via the sides of the housing itself, meaning you do not need to make extra holes in the wall.

How long does the installation of a surface-mounted sunshower take on average?

An experienced installer usually completes the job for a surface-mounted model within two to four hours. Installing a sunshower in an existing shower in this way is therefore a quick upgrade that causes little inconvenience or dust. After installation, you only need to let the sealant edges cure for 24 hours before you can enjoy the beneficial radiation for the first time.
