  • Installing your own Bath

    Installing a new bath is well within the scope of a competent DIYer, but if you are unsure please consult a reputable local plumber for advice and assistance. Tools and materials required include steel wool, a pipe cutter, spirit level, sealant, adjustable pipe wrench, tape measure, adjustable wrench, screwdrivers and pipe joining compound. Begin the job by removing your old bath, turning off hot and cold water at the mains (or isolation valves in the bathroom if fitted) then drain the system by running the bath and sink taps. Then remove any supporting framework and panels from old bathtub and unscrew the taps and waste outlets from the bath using an adjustable tap spanner (if any of the nuts won’t undo you can cut through the pipes but be sure to leave ample pipe for new connections). The next step is to undo the screws holding the bath to the wall and/or floor and lift it away (baths are heavy so two people will be required for this step). Note: before fitting the new bath ensure that you attach earth bonding cable and clamps to all metal pipework and fittings, this is a legal requirement to reduce the risk of electrocution.

    Begin preparing your new bath by assembling it according to the manufacturer’s instructions on a clean, level and soft surface to protect the rim. Fit any handles etc as they cannot be tightened once the bath is in place, then install the waste outlet and overflow and seal with silicone sealant. The last step before putting the bath in position is to fit the taps. Position the timber that the bath will stand on according the manufacturer’s instructions to spread the load of your bath at 90 degrees to the floor joists, then adjust the feet until all the top edges of the bath are level and at the required height. At this point mark any holes for wall fixing and fit the waste trap. Fit the flexible tap connectors and mark the water pipes so you know where they need to be cut then fix the bath’s timber supports using screws. Adjust the waste and water pipes if required and double check tap connections then tighten the flexible tap connectors. Reposition the bath and ensure it’s still level then use silicone sealant between the walls and the bath, then screw any fixing brackets to the wall and screw the feet to the floor. Connect up the waste trap, waste outlet and waste pipe, connect the flexible tap connectors, then turn on the water supply and check for any leaks. Once you’ve finished tiling and the grouting is dry, use silicone bath sealant to completely fill any gaps between bath and wall/tiles – ensure the bath is full of water before doing this job otherwise the position may move slightly with the weight of the water leaving an unsightly gap – leave water in the bath for at least six hours to allow the sealant to dry.
