What we do

Clay trap sinks and plumbing for art and pottery studios in London

Clay and plaster should never reach an ordinary drain. They settle in the pipe, harden and build up until the sink stops draining, often under a floor you would rather not lift. A clay trap sink, sometimes called a plaster or silt trap, catches the sediment in a tub under the basin so you can empty it. We fit clay trap sinks, butler and belfast sink rows, hot water and heating for pottery studios, art rooms, printmaking studios and makers' spaces across London. Our electricians can also wire kiln circuits, so one team handles the lot.

What premises like yours need

What do art and pottery studios need from their plumbing, heating and electrics?

  • A clay or plaster trap on every wash-up sink

    Throwing, trimming, glazing and plaster work all send fine sediment into the sink. Without a trap it settles in the waste pipe and sets hard, especially plaster. A sediment trap sits under the basin and slows the water so the solids drop into a removable bucket or chamber. We size the trap to the number of sinks and how busy the studio is, and fit it where you can actually reach it to empty it.

  • Deep sinks that suit classes

    Studios usually want deep butler or belfast sinks, often a row of two or three so a class can wash up at once. They need solid support, taps high enough to fill a bucket, and wastes that all run through a trap rather than straight to the drain. We plan the run with you, including splashbacks, a drainer or slab for tools, and a place for the bucket that is not in the way.

  • Hot water, WCs and basins

    Washing clay off hands in cold water in January is miserable, and warm water shifts slip and glaze faster. Depending on the space, that might be an under-sink or point-of-use water heater, an immersion cylinder, or a feed from the building's boiler. Staff and students also need working WCs and hand-wash basins. Keep hand washing on a clean basin away from the clay sink where you can, so the trap takes the clay and the WC drains stay clear.

  • Heating and power for the kiln room

    Many studios are in railway arches, old industrial units or draughty church halls. Clay can freeze or crack if a unit gets too cold overnight, and nobody enjoys a class in a coat. Kilns bring their own demands: a suitable dedicated circuit, and for larger kilns sometimes a supply upgrade. Our registered electricians can check what your supply can take before you buy, and our heating engineers can look at radiators, heaters or a new system.

Emptying the trap and knowing when it is full

A sediment trap only works if someone empties it. Busy teaching studios may need to do it weekly, quieter ones less often, so make it part of the closing routine. Signs it is full: the sink drains slowly, water sits in the basin, clay appears in the outlet, or there is a stale or eggy smell from standing water. Scoop or lift out the settled clay, let it dry and bin it or reclaim it, never tip it down a toilet or outside gully. Check the seals and lid when you put it back so it does not leak.

What must not go down the drain

It is an offence to put anything into a public sewer that is likely to damage it or block it, and Thames Water can take action over blockages caused by materials that should not be in the drains. Clay, plaster, glaze and slip all fall into that group. Inks and paints are different: follow the disposal instructions on each product, and never pour solvents, white spirit or oil paint down any sink. Wipe brushes, screens and rollers with rags first, then wash off the last traces in a trapped sink.

Kilns, water supply and ventilation

Before you buy a kiln, get an electrician to look at your consumer unit and incoming supply. A small kiln may run on a dedicated circuit, but larger ones can need more than your supply can safely give, and that can mean talking to the network operator. Separately, the Water Supply (Water Fittings) Regulations require backflow protection matched to the risk, so hoses and sinks used with glazes or chemicals may need suitable protection. Kiln rooms and glazing areas also need decent ventilation; ask the kiln maker what they recommend.

Questions

Questions about plumbing for art and pottery studios

What is a clay trap sink?

It is an ordinary deep sink with a sediment trap fitted under it. Water from the sink runs into a chamber where it slows down, so clay, plaster and glaze settle to the bottom while clearer water carries on to the drain. You lift out the settled material and empty it. It protects your pipes and the public sewer from build-ups that set hard.

Can you fit a trap to the sinks we already have?

Usually, yes. Most sediment traps sit under an existing sink and connect into the waste, provided there is enough space below the basin for the trap and for you to get the bucket or lid out. If the sink is too low or boxed in, we may suggest raising it, moving it, or swapping to a deeper belfast sink.

Our studio sink drains slowly. Is the trap full or is it the pipe?

Empty the trap first, as that is the usual cause. If it still drains slowly afterwards, clay may have got past the trap or built up in the pipe from before it was fitted. We can clear the waste and, if the problem is further down, run a camera through to see where it has collected.

Can you wire a circuit for our kiln?

Our registered electricians can check your consumer unit and supply and tell you what it can take, then wire a suitable dedicated circuit if it is within what your supply can give. Larger kilns can need a supply upgrade from the network operator, which takes longer. It is worth asking before you buy, so the kiln matches what the building can run.

Can you work around our classes and open studio times?

Yes. We can book work early, late, at weekends or out of hours so classes and firings are not disrupted. The price is agreed before work starts, and plumbing, heating and electrical jobs can be done by one team on one visit where that fits, which helps if you are fitting a new sink row with a water heater and circuit.
