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 count

The planner handles custom roll sizes and pattern repeat too — open it for a bathroom sized roughly 2.2m × 1.8m.

Quick roll estimate

Enter your total wall length and height for an instant estimate — standard 53cm × 10m roll, adjustable below.

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.

Can I use any wallpaper in a bathroom?

No. Standard paste-the-paper wallpapers absorb moisture and delaminate in bathrooms. Choose a vinyl-coated or non-woven washable paper rated for humid environments. Some manufacturers specify 'suitable for bathrooms' directly. Always use a fungicidal adhesive to prevent mould forming behind the paper.

How many rolls of wallpaper do I need for a small bathroom?

A typical small bathroom of about 2 × 2.5 m with a 2.2 m ceiling, one door, one window, and a bath along one wall usually needs 4–6 rolls with a plain or small-repeat paper. The actual count depends on how much of each wall is taken up by the bath panel, shower enclosure, or tiling. Use the Wallpaper Planner — enter each paperable wall section separately for an accurate figure.
