What is a straight bath?

Step 3

It’s best to remove the protective cardboard and plastic film at this stage (although you can choose to keep them in place until you’ve fitted the legs, to help protect the bath). Inspect your bath carefully for any damages and check the colour match is acceptable to your suite and any panels.

If you're unhappy with your bath at this stage, please call our Customer Care Team on 0344 804 48 48 immediately (providing you bought the bath from Any refixing costs, claims for wrong colour match, and/or any other faults AFTER installation, will not be accepted.

Step 7

Place the bath against the wall and check that it’s level, adjusting the height of the legs as necessary.

Handy hint: Take a couple of wooden battens up to 60mm wide and stand the bath on these to help protect your floor. If laid on floorboards, these should be at 90 degrees to the joists.
