Saunas, steam rooms and wellness rooms need a floor waste for cleaning and draining down, but they don't want an open grate in the floor the rest of the time. Allproof's 80mm Tile Floor Waste Plug is built for exactly that. It's a solid, cast chrome-on-brass plug that sits in an 80mm Allproof Leak Control Flange in place of a grate, closing the waste off between uses and opening when you need the floor to drain. Round (TFW80PLUGR) or square (TFW80PLUGS), made in New Zealand by Allproof.

Why saunas and steam rooms get a plug instead of a grate

No drain smell in a room built for breathing deeply. A floor waste trap only keeps drain air out while there's water sitting in it. In a hot, dry sauna that water evaporates fast, and an open grate then lets drain air straight into the room. A closed plug puts a solid cover over the opening between uses.

Keeps the steam where it belongs. In a steam room, an open grate is a hole from the room into the drainage. Closing it off helps keep steam and heat in the room during a session.

A finish that suits the room. A polished chrome disc reads as a finished fitting, not a slotted drain. It suits the clean, minimal look of a sauna, steam room, day spa or feature bathroom.

Built to last. It's a cast brass part with a chrome finish, not a plastic grate, so it stands up to a hard-working commercial wellness room as well as a residential one.

Where it suits

  • Residential and commercial saunas
  • Steam rooms in homes, gyms, hotels and day spas
  • Wellness and spa rooms where the floor waste is used for wash-down, not daily drainage
  • Feature bathrooms where a solid chrome finish suits the design better than a grate

What it fits

The plug is 80mm and fits Allproof's Leak Control Flange. The 80mm flange (LC80C) is only $7.00, comes with a construction cap, has locating lugs for the plug, and a large flange area for bonding the waterproofing membrane. Allproof designs its floor waste systems to AS/NZS 3500.2 and the AS 3740 membrane-to-drainage connection details.

The easiest way to get it right is to specify the 80mm Leak Control Flange at rough-in. Then the plug is a straight drop-in at fit-off. Allproof doesn't list the plug for other brands' flanges or 100mm wastes, so for a retrofit, check the existing waste is the 80mm Allproof flange first.

Round or square

Square, 80mm TFW80PLUGS $195.21

Same cast chrome-on-brass part in both profiles. Pick round or square to match the tile layout and the rest of the room's fittings. If the job has a fixed handover date, talk to us about lead time on the profile you want.

Before you specify

  • Open it for wash-down. The floor still needs to drain for cleaning, and a steam generator's installation instructions may call on the floor waste for drain-down. The plug closes the waste between uses; it isn't meant to seal it permanently.
  • The trap and membrane are still the trap and membrane. The gully, trap seal and membrane connection still need to be installed and compliant to AS/NZS 3500.2. Confirm with your certifier how the trap is kept charged in a room that doesn't see regular water.
  • Not for overflow wastes. If a floor waste is required to catch water from a leaking or overflowing fixture, keep it as a grate.

Frequently Asked Questions

What floor waste should I use in a sauna or steam room?

One that drains properly for wash-down but can be closed off between uses. Allproof's 80mm Tile Floor Waste Plug in an 80mm Leak Control Flange does that, with a solid chrome-on-brass finish instead of an open grate.

Will the plug fit my existing floor waste?

It fits Allproof's 80mm Leak Control Flange. Allproof doesn't list other brands or sizes, so check the existing waste before ordering, or specify the LC80C flange at rough-in.

Can I leave the plug closed permanently?

No. Open it for wash-down and draining, and follow any steam generator drainage instructions. If the floor waste is required to catch overflow, use a grate instead.

Round or square?

Same part, different profile. Round is $190.27 (TFW80PLUGR) and square is $195.21 (TFW80PLUGS). Match it to the tile layout and other fittings.
