A point drain is usually the best choice for a standard enclosed shower because it is practical and generally simpler to install. A linear drain often suits walk-in showers, wet rooms, large-format tiles or designs requiring a single-direction floor fall. The right choice must also match the available depth, outlet capacity, pipework and budget. With an existing grate, confirm how to safely remove the shower drain cover before checking the outlet below.
Point drain or linear drain?
| Type | Best suited to | Key considerations |
|---|---|---|
| Point drain | Standard or compact enclosed showers | The floor falls towards one outlet from several directions. Smaller tiles usually accommodate these falls more easily. It is often the economical option when aligned with existing pipework. |
| Linear drain | Walk-in showers, wet rooms and large-format tiles | The channel can support a single-direction fall, but requires accurate positioning, sufficient installation depth and careful coordination with the outlet and pipework. Installation is generally more involved. |
Do not assume a longer linear drain has greater capacity. Performance depends on the complete shower grate, channel, outlet, trap and connected pipework. Check the manufacturer’s rated flow for the complete assembly against the combined discharge from the shower fittings. If the problem is odour rather than flow, check why a shower drain smells before replacing the drain.
What determines suitability?
Choose the drain before plumbing rough-in, screeding, waterproofing and tiling are finalised. A late change can affect the outlet position, floor levels and falls.
Consider:
- Layout and falls: The drain position and floor falls must direct water to the outlet without ponding or allowing water to escape an open shower area.
- Tile format: Small tiles accommodate multi-directional falls around a point drain more easily. Large-format tiles often work better with the single-plane fall possible with a linear drain.
- Outlet capacity: Confirm the rated performance of the complete drain assembly and compatibility with the trap and downstream pipework.
- Floor construction: Concrete slabs, suspended floors and limited recess depth can restrict drain placement. Existing pipework may make a point drain more practical.
- Finish: Tile-insert drains provide a discreet appearance but must retain access to the channel. Stainless steel is a durable option when the product and finish are rated for wet-area use.
- Budget: Point drains are generally less expensive to purchase and install. Linear drains often require more detailed floor preparation and coordination.
Homeowners can select the layout and finish, but should not alter sanitary plumbing or undertake regulated wet-area work. Use appropriately licensed NSW tradespeople for the work involved.
