We trim the flange (the flat rim) on the side(s) of your Omnitub that sit against a wall, for a clean built-in fit. Priced £75 including VAT per cut — one side is £75, two sides £150, three sides £225. You choose which wall sides and how much to trim (down to a 25 mm minimum flange) in the Drawing Room.

Flanges are only trimmed where a side goes against a wall — never on an accessible side. Trimming reduces the space behind the tub, so it can limit where an overflow or tap holes can go on that side. Once trimmed, your Omnitub is a made-to-order bespoke item and is non-returnable, except for damage in transit. An installer can also cut the flanges on site with our guide using a diamond-cut blade — having us do it simply saves a process.
