Shower Tray Heat Recovery Retrofit
Simple, effective heat recovery for refurbishments, flats and ground-floor showers.
Shower tray heat recovery retrofit is about capturing energy that would otherwise be lost down the drain — without the upheaval of a full system replacement. For refurbishment projects, flat conversions, and ground-floor shower installations, a retrofit heat recovery tray offers a practical path to improved energy efficiency. Rather than installing a separate heat exchanger unit under the floor, the Sanura range integrates recovery directly into the shower tray, making it an ideal choice where space is limited or access is restricted.
Energy recovery built in
Sanura shower trays recover heat from waste water as it leaves the shower, warming the incoming cold water supply and reducing the energy needed to heat it.
Retrofit-friendly installation
Designed for straightforward fitting in existing bathrooms, the integrated design reduces the need for sub-floor work and complex plumbing changes.
Ideal for flats and apartments
Where access is limited or floor space is at a premium, a retrofit tray eliminates the need for bulky separate heat exchangers, making it a clean solution for multi-occupancy buildings.
Sanura retrofit solutions for every project
The Sanura range includes two key products for retrofit applications:
- Sanura Flatmate — a compact, shallow tray designed specifically for retrofit and low-profile installations. It suits ground-floor showers, basement bathrooms, and conversions where floor build-up is minimal.
- Sanura X-tray XL — a larger format tray offering the same integrated heat recovery for bigger shower enclosures, ideal for accessible bathrooms or commercial refurbishment work.
Both products share a common approach: recovery is built into the tray structure rather than added as a separate component, which simplifies installation and reduces the number of parts to maintain.
Typical project scenarios
Flat or apartment conversion with restricted floor depth. Ground-floor shower room in an existing house. Refurbishment of a communal shower area in a retirement or assisted living facility.
