Where bath mats should go, what size to choose and how to lay them out in a small bathroom, a double vanity or a bathroom with a tub, with measurements you can use.
Put your largest mat where you step out of the shower or tub, a smaller mat centered in front of the sink, and a U-shaped mat around the toilet base. Keep every mat clear of the door and walkways, lay them flat without overlapping, and measure the floor first.
Almost every bathroom has three spots where the floor gets wet or cold: the shower or tub exit, where most water lands; the sink, where you stand every morning and night; and the toilet. Start with the exit, because that’s where a mat does the most work.

| Where | Common size | Mattona™ piece |
|---|---|---|
| Shower or tub exit | About 50 × 80 cm (20 × 32 in) | Bath mat, 81 × 50 cm (31.9 × 19.7 in) |
| In front of the sink | About 40 × 60 cm (16 × 24 in) | Floor mat, 60 × 43 cm (23.6 × 16.9 in) |
| Around the toilet | U-shaped contour mat | U-shaped mat, 60 × 50 cm (23.6 × 19.7 in) |
| Double vanity | A long runner, or two mats | Two floor mats, one per sink |
For the shower or tub exit, pick a mat at least as wide as the step-out area, so your first steps land on it. At the sink, a mat roughly the width of the basin area is plenty.
One larger mat at the shower door and one smaller mat centered on the sink. If the toilet is close by, a U-shaped mat completes the set.
Put the largest mat alongside the tub where you step out. For the vanity, use a long runner or two mats, one per sink, with a small gap between them.
Use fewer, smaller mats, and put the one you most need at the shower exit. Keep the door swing clear: a mat that catches the door gets pushed out of place and can curl.
A U-shaped mat alone is often enough. Check that it doesn’t catch the door. Here’s how to check the fit.
More on the set itself: where each piece of a 3-piece set goes.
Not necessarily. Center the mat on the sink where you stand. For a double vanity, use a long runner or one mat per sink.
Keep a rectangular mat clear of the toilet base so it lies flat. If you want coverage around the base, use a U-shaped toilet mat instead.
Yes, but leave a small gap between them so the edges can’t overlap or curl.
A smaller mat, around 40 × 60 cm (16 × 24 in), at the spot you use most, usually the shower exit. Make sure the door clears it.
