Yes, concealed shower mixers in HDB flats are generally possible, but the installation has to follow HDB renovation requirements and PUB plumbing rules. Because part of the mixer and pipework sits behind the wall, more planning may be required compared with an exposed shower mixer.
A concealed mixer gives the shower area a cleaner appearance because most of the working parts are hidden behind the finished wall, leaving mainly the controls visible.
First check what work is needed behind the wall
Installing concealed shower mixers in HDB flats may involve work to the wall and existing water pipes. This should therefore be discussed with your contractor before tiles and other bathroom finishes are completed.
Things to consider before choosing a concealed mixer:
- Position of the existing water pipes
- Depth required for the built-in mixer
- Location of the shower controls
- Access for future servicing
- Whether wall finishes need to be removed
Bathroom Warehouse carries concealed shower mixer sets and built-in components from brands such as Duravit and GESSI, giving homeowners several concealed and exposed options to compare.
Take note if you have a new BTO
For newly built HDB flats, there is a 3-year restriction on removing the original wall and floor finishes in bathrooms and toilets. HDB states that these finishes provided by HDB or the developer should not be replaced during this period.
This can affect the installation of concealed shower mixers in HDB flats if the proposed work requires removing or altering the original bathroom wall finish. It is therefore better to let your renovation contractor check what can be done before purchasing the mixer.
Check the plumbing requirements
PUB requires regulated water service and sanitary plumbing works to be carried out by a Licensed Plumber. PUB also requires water fittings supplied for use in Singapore, including taps and mixers, to comply with its stipulated standards and requirements.
This is especially relevant to concealed shower mixers in HDB flats because changing the existing pipe arrangement may involve more than simply replacing an exposed mixer.
Should you choose a concealed shower mixer?
If you prefer a neat and minimalist shower area, concealed shower mixers in HDB flats can be considered. However, the plumbing route, wall construction and access for maintenance should be checked beforehand.
For a new BTO, the 3-year bathroom restriction should also be taken into account. Ultimately, concealed shower mixers in HDB flats are best planned together with your contractor and Licensed Plumber before renovation work begins.
