● Double-ended baths: usually rectangular in shape but they have two ends
and are designed with two people in mind.
● Tapered baths: designed for situations where space is limited. They are
wider at one end than the other, and are usually fitted with a shower at the
wider end.
● Shower/baths: again, usually bulged at one end to maximise the space
available for showering.
The most common sizes range from 1600 mm to 1800 mm in length and

Tap hole and waste arrangements for baths
Tap holes for baths come supplied in three ways:

1 no tap hole – this type of bath needs to be drilled so the taps can be installed
in the position of the customer’s choice
2 two tap hole – the standard arrangement; they can be either on the end of
the bath or the side
3 three tap hole – for remote-type taps (one hole for the spout and two holes
for the taps).
Waste connections for baths can be made by the following methods.
● ‘Banjo’-type bath waste fitting: this uses a long threaded waste fitting
with slots on opposite sides near the top. The waste from the overflow
comes via a flexible pipe connected by a ‘banjo’ connection. This is
assembled over the waste fitting and is held in place on the underside of
the bath by a large 1½-inch BSP nut fitted to the bottom of the waste
fitting and tightened against the banjo. Silicone sealant should be used at
p Figure 9.46 The ‘banjo’-type the joint between the bath and the banjo, and the banjo and the nut. This
bath waste fitting type of bath waste connection is very prone to leakage.
