Types of Bathrooms

Bathrooms can be categorised into several different types based on their size and function. The smallest footprint for a bathroom is usually the powder room and the half bath. There are plenty of variations depending on the type of fixtures present like the three-fixture bathroom, compartment bathroom, powder room, utility bathroom (with laundry facilities), large bathroom and bathroom that is accessible to the physically challenged and many more.

3 fixture Bathrooms

The conventional three-fixture bathroom without compartments is designed for use by one person at a time. The three fixtures can be a Washbasin, a Toilet and a shower cubicle or a Washbasin, a Toilet and a Bathtub-with-or-without-shower.
There are different ways of arranging the fixtures in a Bathroom. The best arrangement in terms of using the space efficiently is having the three fixtures in a row against the wall opposite the door.
For a bathroom with washbasin in the centre and toilet and bathtub/shower on either side, the minimum size required is 7’4″ x 5’6″. In this type, the door is in the centre of the wall opposite the washbasin.
For a bathroom with washbasin first, then toilet and lastly bathtub/shower, the minimum size required is 7’8″ x 5’0″ (for a shower type) and 8’0″ x 5’0″ (for a bathtub type). In this type, the door to the toilet is opposite or adjacent to the wash basin.
For a square type bathroom, with shower cubicle in one corner and wash basin on one wall and the toilet on the other wall, the minimum size required is 6’0″ x 6’6″.
For a square bathroom, with bathtub in one corner, wash basin on one wall and toilet on the other wall, the minimum size required is 6’0″ x 8’0″.


Compartment bathrooms

To avoid excessive humidity in the usual three-fixture bathroom, the bathtub or shower cubicle is located in one compartment with a separate door, while the toilet and Washbasin are located in another compartment. This type of bathroom affords privacy for 2 users using the bathroom, at the same time and prevents the build-up of humidity in the whole bathroom. The minimum size of such a bathroom is 10’6″ x 6’0″.

  • Another variation is to have 2 separate bathrooms with separate doors – one with only the toilet, (the minimum size of the Toilet is 3’6″ x 5’0″) and the other with the Shower/bathtub and washbasin,(the minimum size is 5’6″ x 6’0″). In this type, the bath can become a combination bath-dressing room. This system was very prevalent in India earlier because it is recommended in Vastu Shastra.


Guest Bathrooms

Also called “1/2 bath” or “guest bath”, it usually refers to a two-fixture bathroom, with only a Toilet and a Wash Basin meant for guests. The minimum size of a powder room is 5’0″ x 5’0″. It is usually located close to the living/dining room to allow easy access to guests.


Utility Bathrooms

This bathroom is a three-fixture one but has additional space to allow other functions like laundering, dressing etc. The minimum size of a bathroom with a shower cubicle, a washbasin, a toilet and a dressing area/drying cabinet/linen cabinet/extra washbasin is 6’6″ x 7’6″ and with a bathtub, it will be at least 9’6″ x 6’6″ or 11′ x 5’6″.


Large Bathrooms

A Four-fixture bathroom – a toilet, a bathtub and 2 washbasins (His and Her’s) will be 10’0″ x 7’2″ or 12’2″ x 5’0″.


A Five-fixture bathroom – with a bathtub, 2 toilets and 2 washbasins in separate compartments will be around 16’4″ x 5’0″ or 11’0″ x 8’0″
