What Is a Powder Room in a House? Meaning, Size and Tiling
A powder room in a house is a small washroom containing only a toilet and a basin — no bath, no shower — placed near the living and dining rooms for guests. It is the room visitors actually use, which is why it is worth more attention per square metre than any other room in a house.
Powder rooms in Indian houses
In Indian homes the powder room is usually called the guest toilet or common toilet, and it has become a standard feature of villas, duplexes and larger apartments. It sits off the living or dining area so that guests do not need to walk through bedrooms to reach an attached bathroom.
On architects' floor plans it is often labelled PWDR or "pwdr room" — simply an abbreviation of powder room — alongside WC, TOI and BATH. If a plan shows a PWDR near the entrance with only a WC and basin drawn in it, that is the guest washroom.
Because there is no shower, a powder room stays dry and needs no floor slope or waterproofing on the scale of a bathroom. That frees the budget for finishes: a statement basin, a feature wall and good lighting make more difference here than anywhere else in the house.
Where the name comes from, and what it means now
The term dates from the eighteenth century, when guests would retire to a small private room to have their wigs re-powdered. The wigs went; the room and the polite euphemism stayed.
In modern usage — mostly North American, but increasingly understood everywhere — a powder room is a small washroom with a WC and a basin and nothing else. It is on the ground floor, near the entertaining rooms, and it exists so guests never have to go upstairs or into a family bathroom.
British and Indian English generally call the same room a cloakroom, a guest toilet or simply a WC. An American estate agent will call it a half bath, counting a full bathroom as four fixtures (WC, basin, bath, shower), a three-quarter bath as three, and a half bath as two.

Tiling a powder room
- Tile it fully — this is the room to spend on — It is small enough that a premium tile costs very little in total and it is the room guests actually see.
- Large format, not small — Fewer joints make a tiny room read as one surface. 600x1200 mm in a 0.9 m wide room sounds wrong and looks right.
- Gloss walls if there is no window — Most powder rooms are internal. A polished wall tile bounces what light there is and stops the room feeling like a cupboard.
- Still specify R10 on the floor — A basin means splashes. Gloss walls, matt floor.
- A feature wall works better here than anywhere — One book-matched marble-effect wall behind the basin transforms the room, and the area is so small the cost is trivial.
- Wall-hung fixtures buy visual space — Clear floor under a wall-hung WC and basin makes the room read substantially larger.
- Extraction is not optional — No window means mechanical ventilation, or the grout will grow mould whatever you clean it with.
Frequently asked questions
What is a powder room in a house?
A small washroom with only a toilet and a wash basin — no bath or shower — placed near the living and dining rooms for guests. In Indian homes it is often called the guest toilet or common toilet.
What does PWDR mean on a floor plan?
PWDR is the abbreviation for powder room: a guest washroom with a WC and basin only. A "pwdr room" on a house plan is usually close to the entrance or living area.
Why is it called a powder room?
From the eighteenth-century practice of retiring to a small private room to have a wig re-powdered. The wigs disappeared; the polite name for the room did not.
What is the difference between a powder room and a bathroom?
A powder room has two fixtures — WC and basin. A full bathroom has four, adding a bath and a shower. American estate agents call a powder room a half bath for exactly this reason.
What is the minimum size for a powder room?
About 0.8 x 1.4 m, roughly 12 square feet. That allows 380 mm from the centre of the WC to each side wall and 530 mm of clear floor in front of it, which is the practical floor below which the room fails inspection.
Is a powder room the same as a cloakroom?
Effectively yes. Powder room is the North American term, cloakroom the British one, and guest toilet or WC the usual description elsewhere. All describe a small washroom with a WC and basin only.
