Bathroom Dimensions Guide: Standard Sizes for Showers, Sinks and Toilets
MEEZ Mimarlık Team5 min read
How big should a shower stall be, and how much clearance does a toilet need in front? Another missing piece in our dimension guide series: standard bathroom and wet area sizes.
The bathroom has one of the smallest footprints in a home but the least margin for error — a miscalculation of just a few centimeters can leave a shower door unable to open all the way, or no room left to turn around in front of the sink.
Standard dimensions for fixed fixtures
| Fixture | Common size |
|---|---|
| Shower stall (square) | 80×80 – 90×90 cm |
| Shower stall (rectangular) | 70×100 – 90×120 cm |
| Bathtub | 150–170 cm long, ~70 cm wide |
| Sink (single) | 45–60 cm wide |
| Toilet (front-to-back) | ~65–70 cm deep |
Clearance and circulation space
- In front of the sink: Leave at least 60–70 cm of clear space for comfortable use.
- In front of the toilet: At least 60 cm of clearance — enough to stand up and sit down comfortably.
- In front of the shower: Leave clear space roughly equal to the stall's width so the door can open fully (sliding doors need less).
- Wheelchair-accessible wet area: A wheelchair needs a clear turning circle of at least 150 cm in diameter.
Practical solutions for a small bathroom
- Swapping a bathtub for a shower stall frees up a noticeable amount of circulation space in the same footprint.
- A wall-hung toilet with a concealed cistern creates more visual floor space and is easier to clean.
- Mounting the sink cabinet on the wall (without legs) makes the floor area look larger.
- Sliding shower doors need less clearance than hinged ones — a good choice for tight bathrooms.
These dimensions complement the bathroom/WC minimum area table in our Minimum room size in square meters article; together, they can guide both the total area and the interior layout of a wet area.
