How can you optimize space when fitting a small bathroom? Installing a bath can still be possible! For this project, the whole 3m2 bathroom was ripped out and new flooring was installed. If you are going to tile a floor like the one below, you will need 18mm plywood, durabase matting for crack prevention and flexible tile adhesive. With the client we decided on a vanity unit and sink with minimal depth to optimize space. No soil pipe was available for this end of the building and so a saniflow was required for the toilet. A standard 1m70 bath with a thermostatic shower valve was installed. At the end of the bath, there was a small area of space to be utilised so i created a cubby hole to store towels.
