Believe it or not, you only need a space 70cm wide and 130cm long to install a toilet – downstairs or upstairs! However, as you can imagine, this doesn't leave much room for anything else, so we recommend building one a bit bigger to make your, erm… experience more comfortable.
In a toilet containing only a commode and a wash basin, such as in a powder room, a 5' X 4' size is the minimum requirement. Instead of following this size, a toilet no narrower than 3' can also be designed, keeping in mind that the minimum area required for this toilet without a shower will be 20 square feet.
Toilets: Similar to wash basins, allow 20 cm on both sides for room to move. A 60 cm space is needed in front of the toilet. Bath tubs: A free-standing model needs 55 cm space all round so that people can experience its full effect. A standard bath tub is roughly 170 x 75 cm in size.
Back to wall toilets are a great option to consider for small spaces. These toilets are designed in a way that allows you to hide the cistern behind a wall or within a WC unit, leaving only the toilet bowl visible.
