Combination Vanity Units

A combination vanity unit puts the basin and the toilet into a single run of furniture, hiding the cistern and all the pipework behind one continuous front. It is the tidiest way to finish a small or medium bathroom, and usually cheaper than buying the pieces separately.

Choosing a width

Overall widths typically run from 1100mm to 1500mm. The basin section and WC section are sized within that, so check both if you have a specific space to fill. Measure the full wall run including any skirting you will need to notch around.

Left or right hand?

Combination units are handed — the basin sits either left or right of the toilet. Stand facing the unit and decide which side the basin needs to be on, bearing in mind door swing and where the existing soil pipe runs. Getting this wrong is not something you can correct on site.

What is included

Most sets include the basin unit, WC unit, worktop and basin. The toilet pan, cistern and seat are often extra, as are taps and the flush plate. Check each product page carefully before assuming.

Fitting notes

The soil pipe position dictates almost everything, so establish it before ordering. Combination units are back-to-wall, so the pan must suit that arrangement — see our back to wall toilets.
