On a plastic bath, it is likewise reasonable to fit a supporting plate under the taps unit to prevent strain on the bath bath.

Fit the versatile tap adapters to the bottom of the two taps using 2 nuts and olives (often provided with the bath).

Fit the plug-hole outlet by smearing mastic filler round the sink outlet hole, and then pass the outlet through the hole in the bath. Use the nut provided by the manufacturer to fit the plug-hole. Take a look at the plug-hole outlet for an inlet on the side for the overflow pipeline.

Removing Old Taps


If you require to replace old taps with new ones as a part of your installation, then the first thing you need to do is disconnect the supply of water. After doing so, turn on the taps to drain any water remaining in the system. The process of removing the existing taps can be rather problematic due to the restricted access that is frequently the case.

Use a basin wrench (crowsfoot spanner) or a tap tool to reverse the nut that links the supply pipelines to the taps. Have a fabric ready for the remaining water that will come from the pipelines. Once the supply pipelines have actually been removed, use the exact same tool to loosen up the nut that holds the taps onto the bath/basin. You will require to stop the single taps from turning throughout this procedure. Once the taps have been eliminated, the holes in the bath/basin will need to be cleaned up of any old sealing substance.

Prior to proceeding to fit the new taps, compare the pipeline connections on the old taps to the new taps. If the old taps are longer than the brand-new taps, then a shank adapter is needed for the brand-new taps to fit.

Installing the Bath

Once the tap is firmly in place, the supply pipelines can be connected to the tails of the taps. The taps can either be linked by using corrugated copper piping or with regular tap ports. The previous type should be connected to the tap ends first, tightening only by hand. The supply pipes can later on be connected to the other end. Tighten up both ends with a spanner after both ends have been linked.

Tiling Around the Bath

In the location where the bath meets the tile, it is essential to seal the accompanies a silicone rubber caulking.
