A-Z of bathroom renovation terms

There’s lots to know when planning your bathroom renovation—from planning through to styling. To help, we’ve put together a list of common terms you might hear during your renovation.

Basins

1-tap hole basin
Basin suitable for mixers only. Abbreviated to 1TH.

3-tap hole basin
Basin with provision for 3-piece tapware. Abbreviated to 3TH.

Above counter basin/vessel
Basin mounted onto a benchtop with all or most of the basin above the benchline.

Inset basin/vanity basin
Installed into the vanity benchtop with the outside rim above the benchline.

Overflow
A drainage point positioned near the top of the basin to prevent overflow.

O tap hole basin
Basin with no provisions for tapware. Used with wall or bench mounted taps, such as a tower basin mixer. Abbreviated to NTH or OTH.

Semi-recessed basin
Recessed into the vanity benchtop, extending past the front edge. Ideal for narrower vanity units.

Under counter basin
Designed for installation on the underside of a benchtop. Particularly applicable to stone benchtops.

Wall basin
Installed fixed to a wall, without the need for a vanity. Ideal for small spaces.

Baths

Bath hob
The structure that the bath sits in.

Freestanding bath
Sits directly on the bathroom floor with no adjacent support structure. Can be installed back-to-wall (depending on design), away from the wall or in the middle of a room. Normally supported by feet or a bath base.

Inset bath
A bath where the tile flanges are inset into an adjoining wall.

Island bath
Bath sits on a brick or framed surround without any of the flange of the bath’s sides adjoining a wall.

Overflow
A drainage point positioned near the top of the bath to prevent overflow.

Tile flange bath
A raised edge of the shower base or bath found on one or more sides of the base or bath. The flange forms an integral part of the waterproofing system when abutted to or checked into a wall. Essential when installing an overhead shower.

Showers

Diverter
In-built mechanism within the shower system allowing the user to direct water flow to an overhead drencher, a handset or a bath filler.

Exposure rail shower/shower systems
Exposed rails and showerheads allow for easy installation and upgrading. Enjoy the flexibility of a rail shower with the choice of an overhead drencher. Adjustable in-built diverter gives you whatever shower experience you desire.

Hand shower
Offers the functionality of a fixed-point shower with the versatility of a moveable showerhead. Includes a handset on a hose that can be placed in a holder to act as a wall shower, or as a fully manoeuvrable shower on a hose.

Hi-rise shower
Practical, functional and adjustable, it includes a shower rose attached to an arm that’s height and angle adjustable, allowing for a range of showering options.

Overhead shower
A showerhead mounted to a shower arm. This allows for a vertical, rain-like showering experience and wide spray coverage. Also known as a drencher.

Rail shower
Offers the flexibility of a height adjustable shower with a moveable handset for premium control and performance. Hand shower is mounted onto a rail on which it can slide, allowing easy height adjustments.

Shower rose
A showerhead attached to a shower arm. Shower roses can’t be fixed directly onto a wall outlet.

Wall shower
An ideal choice for a confined area, due to its compact, sturdy qualities. Consists of a shower rose attached to a fixed shower arm.

Tapware

3-piece taps
Includes a separate hot tap, cold tap and spout. Temperature and flow adjustments are made by turning each individual tap to achieve the desired temperate and flow setting.

Ceramic disc
These provide precise water control so you get just the right amount of water at the right temperature. Ceramic disc technology ensures a watertight seal, eliminating drips, minimising product maintenance and ultimately saving water and energy.

Mixer tap
Combines the spout and temperature handle in one unit. One lever controls both temperature and water flow.

Pedestals
Optional extra for a wall basin. Located between the basin and the finished bathroom floor. A pedestal is often installed to conceal plumbing and add style to the bathroom space. Provides no support to the basin and does not sit flush against the wall.

Shroud
Has the same function as a basin but shorter in length. Designed to conceal the plumbing fittings only. In most cases, it doesn’t sit flush against the wall.

Temperature limiting device
This spring-loaded cartridge ensures a pre-determined, comfortable temperature when the mixer is turned on. Also prevents small children from accidental scalding.

Toilets

Back inlet cistern
Water inlet connection is from the wall directly into the back of the cistern. The connection is completely concealed and has an integrated stop valve.

Bottom inlet cistern
Water supply to the cistern is available via the underside of the cistern.

Box rim
Closed water rim with inlet holes around the underside to direct water into the bowl of the pan. Quiet operation and with excellent water distribution for bowl rinsing.

Closed couple suite
Pan and cistern are joined together so that the flush pipe isn’t visible.

Connector suite
The flush pipe is hidden with a connector plate so that the toilet looks like a close-coupled toilet suite, but with greater flexibility in how the toilet is laid out.

Drop zone
The toilet bowl surface area has been designed for superior flushing performance and to minimise cleaning.

In-wall cistern (concealed suites)
In-wall cisterns are hidden in the wall, with only the pan and flush buttons visible. Use either wall hung and wall face pans.

Open rim pan
Open rim pan with flushing rim that directs water to the front of the pan and allows water to fall freely over the bowl for rinsing.

P-trap
A toilet waste outlet that extends through the back wall.

S-trap
A toilet waste outlet that extends through the floor.

Set out
This dimension details the position of the plumbing pipework and is essential when choosing your toilet, especially if you’re not changing the location of plumbing.

Skew trap
A toilet waste outlet that extends through the side wall, either on the left or right hand side.

Uni-orbital connector
Overcomes set out incompatibility when selecting a new toilet suite. Uni-orbital connector extends a toilet set out to any position within a 50mm radius, allowing greater installation flexibility by rotating the upper and lower bodies.

Wall-faced suite
Pan is installed flush against the wall.

Wall-hung suite
Pan is suspended above floor level and installed directly to the wall. This is only available with in-wall cisterns.

WELS rating
