Bathroom Wallpaper Calculator
Bathrooms are small but need moisture-resistant wallpaper and careful cutting around fixtures — here’s what to expect when you plan one.
Get my bathroom roll countThe planner handles custom roll sizes and pattern repeat too — open it for a bathroom sized roughly 2.2m × 1.8m.
Use vinyl or vinyl-coated paper
Standard paper wallpaper isn't rated for bathroom humidity — make sure your roll is labelled washable or vinyl.
Fixtures eat into your strip count
Sinks, toilets and cabinets reduce usable wall area more than a simple opening-width estimate captures — treat a large vanity like an extra door.
Small rooms round up more
On a room this size, expect some leftover roll, which is worth keeping for future repairs.
Common questions
Can I wallpaper around a shower?
Only with a fully waterproof/vinyl product rated for direct wet contact, and only outside the direct spray zone. Check the manufacturer's rating first.
Why does a small bathroom still need 2+ rolls?
Rolls are sold as fixed lengths, and short walls waste more of each roll on off-cuts — small rooms are often less roll-efficient than large ones.
