Shower mixer and tap leak protection that closes the gap around wet area penetrations
Waterproofing membranes are routinely specified for wet areas, but the penetrations created for mixers and outlets can be overlooked.
Wetwall Caddy provides a defined cavity protection detail around these openings, helping prevent water from tracking behind the wall lining and into framing. The caddy is an accessory to the wider waterproofing system, not a replacement for the membrane.
It also gives the plumber, waterproofer and tiler a consistent point to work to, reducing the need for the penetration detail to be resolved differently on each site.

Straightforward installation for tiled and acrylic systems
Wetwall Caddies are fitted at framing stage and typically take around 10 minutes to install.
For tiled showers, the caddy is fixed before the wall lining is installed. The flange then sits over the lining before the waterproofing membrane and tiles are applied. The access opening is cut to suit the requirements of the selected mixer.
For acrylic lined showers, the caddy is positioned at the correct depth before the wall lining and acrylic liner are fitted.
Technical information for specification and consent
Wetwall Caddy is designed to make the penetration detail easier to specify, document and repeat across projects.
Technical resources include tiled and acrylic installation details, specification information, installation guidance and supporting product documentation. These can be used by builders, plumbers, waterproofers, designers and other project professionals when detailing wet areas.
Wetwall Caddy is referenced within the New Zealand Building Code acceptable solutions E3/AS1 and E3/AS2. Full compliance information and current technical documentation are available through the Resources section.
Maintain service access and reduce future disruption
The access opening around a mixer is there for a reason. Cartridges, ceramic discs and other components may need servicing over the life of the tapware.
Wetwall Caddy protects the wall penetration while preserving access from the front, helping avoid the need to break tiles or open the finished wall to carry out routine servicing.
For builders and plumbers, this provides a clearer installation detail from the outset while helping reduce the risk of future callbacks associated with hidden water entering around wet area penetrations.
The mixer penetration is where water can get behind the wall lining. Wetwall Caddy seals that opening while keeping front access available for servicing cartridges and ceramic discs.
No. The caddy is a component within the waterproofing system. The membrane is still applied, with the caddy providing a defined stop point for sealing penetrations.
Stock units suit about 98% of shower mixers. Inline, basin and apartment layouts can be covered by a custom Wetwall Caddy printed to order from the tapware product code.
