How to Choose an Over-the-Washer Basin

Choosing an over-the-washer basin

In a small bathroom, every inch counts. One of the most popular ways to save space is to install a basin over the washing machine. It not only saves space but also creates a tidy, functional interior. In this guide we'll look at how to choose the right basin, what to watch for, and the details worth considering before you buy.

Why choose an over-the-washer basin?

Space-saving — an ideal solution for a 2–4 m² (20–43 sq ft) bathroom.

Functionality — convenient to use the basin and washing machine at the same time.

Stylish look — modern models create a clean, harmonious composition.

Lower remodeling costs — sharing the water and drain connections reduces plumbing work.

What types of over-the-washer basins are there?

Artificial stone
Strong and heavy (from 15 kg / 33 lb), with a pleasant texture and a premium look; it dampens the sound of running water well.

Cast acrylic
Lightweight (up to 5 kg / 11 lb), impact-resistant, warm to the touch, and doesn't absorb moisture or household chemicals.

Ceramic
A classic option, easy to clean, but fragile on impact and less convenient to mount and use.

What to look for when choosing

Dimensions

Width: washing machines are most often 60 cm (24 in). The basin should also be 60 cm — or 51 cm (20 in) for compact machines (the PROTON by Redokss San).

Basin depth: ideally 50–55 cm for machines 35–40 cm deep, so the basin doesn't stick out too far while staying comfortable to use.

Overall height: the basin and machine together should sit about 85–95 cm from the floor, allowing for the gap between them.

Material

Choose the material based on your budget, interior style and how it will be used. Cast acrylic — ideal for everyday use and budget-friendly. Artificial stone — for those who value a solid, monolithic look. Ceramic — a classic, but handle with care.

Drain type

Best option — a drain behind the washing machine.

Acceptable compromise — a side drain.

Least convenient — a drain above the machine (it can get in the way during installation).

Siphon

These basins require a flat (slimline) siphon. It doesn't take up space behind the machine and lets you place it as close to the wall as possible.
