Whilst plumbing and installation is best left to a qualified professional, if you’re competent at DIY, you can still save time and money on your bathroom installation cost by fitting your new bath.

There are a great variety of baths on the market for you to choose from, with different styles, shapes, and purposes. For example:

For the purposes of this how to guide, we’ll be looking at fitting a straight bath.

What is a straight bath?

A straight bath is one of the most common baths you’ll find in the UK. Usually constructed out of acrylic or sometimes steel, it sits on legs which are then concealed by bath panels. Taps are found either at one end (in a single ended bath) or on one side (in a double ended bath).

The Kensington is a good example of straight, single ended bath

Fitting your straight bath

At VictoriaPlum.com, you’ll find most of our straight baths are crafted from high quality, acrylic that’s warm to the touch, and has excellent impact and scratch-resistance for superb durability.

The following video and instructions are for fitting a straight bath:


Step 1

Place your bath on a level surface.

Step 2

Remove the fittings box (usually attached to the underside of the bath) and check you have all the components.

Step 3

Remove the protective cardboard and plastic film. Inspect your bath carefully for any damages and check the colour match is acceptable to your suite and any panels.

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

Step 4

If the bath has handles, fit them now.

Step 5

Attach the bath legs to the brackets.

Step 6

Attach the brackets to the underside of the bath.

Step 7

Attach the centre leg.

Step 8

Roughly adjust the height of the legs to match your desired bath height using a tape measure. 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.

Step 9

Mark your desired bath height on the wall with a pencil.

Step 10

Offer the bath up to the wall, check that the bath is level using your spirit level and make further adjustments to the legs as required.

Step 11

Attach the wall fixing brackets, as per your instructions.

Step 12

On the bath top, just above the overflow hole, mark the overflow centre with a pencil.

Step 13

Measure the distance between the tap inlets and transfer this measurement to the bath top, just above the overflow hole, with a pencil.

Step 14

Where you have marked your tap inlet measurements, measure the centre point of the bath lip and mark in pencil. This will form a cross between the 2 measurements, forming the centre point for your tap holes.

Step 15

Drill holes for your tap inlets with an electric drill and hole cutter, using each cross as the centre point.

Step 16

Fit your bath tap(s).

Step 17

Fit the waste and overflow, and make a note of any adjustments that will be required to the waste pipe.

Step 18

Position the bath in place and secure to the wall and floor.

Step 19

Plumb in your taps and waste (leave this part to a professional plumber).

Step 20

Turn the water back on at the mains. Check for leaks by closing the waste and running a bath.

Step 21

Tile down to the bath and seal round the edges with silicone sealant. Handy hint: Fill the bath with water before sealing it. The weight of the water will help create a good watertight seal.

Congratulations! You’ve now fitted your straight bath.

Whilst DIY can be a good way to save time and money, you should always hire a qualified professional to plumb and install your products. The instructions above are simply a guide to fitting your new bath and shouldn’t be used to attempt full plumbing and installation.
