Planning & Specification - Determining Type of Drainage

 

An interconnected system

One of the most important decisions to consider with a bathroom, is how to incorporate drainage into the design. The solution must fit the bathroom floor layout to ensure it functions properly.

For a bathroom with a single primary drainage trap, there are two types of bathroom drains. A trapped central floor waste (overflow gully) and other waste outlets from a bathroom’s fixtures (showers, basins, bathtubs etc.). The drains from these fixtures (secondary drainage) are connected to the central floor waste (primary drainage). These form part of a bathroom’s interconnected pipe system.

Some bathrooms are plumbed with separate traps to each fixture.

Traditional floor wastes

Floor wastes offer a point outlet, typically located at the centre of the shower area and/or bathroom floor.

Generally a cheaper initial product cost

Usually not appropriate for level threshold applications

Requires traditional tiled threshold step / hob to contain water

Tiling can be complex, typically requiring careful 4-way grading of the floor

Increased tile wastage due to diagonal cutting and lipping requirements to AS3958

Higher flooring cost due to extra time required to produce a 3D floor plan

Linear drains

A linear grate and channel can be located anywhere within the shower area and requires simple 2D grading of the floor towards the channel.

Usually a higher initial product cost, but reduced tiling cost due to decreased installation time

Level threshold can be created for easy wheelchair/disabled access

Can be used to separate wet from dry areas

Can be used with any type of tiled shower configuration

Tiling is simplified with minimal cuts required and less wastage

Easy to use with any tile size and material
