Plumbing and Electrical Requirements

Plumbing and electrical requirements for your steam or shower cabin...


Please Note: A fully comprehensive installation guide comes with your shower purchase - either as a printed or downloadable PDF - but here are a couple of main points below, regarding electrics and water. In the main, this information is in regards to steam showers with thermostatic cartridges and electrical features.

If you are purchasing a non-steam shower cabin, some of this information may not apply [i.e. no electrics required, if the model chosen has no electrical features and/or a mixer control valve]. Always check the full specification of the model first.

Electrical Details: All steam shower cabins require a 13amp electrical supply feed. The shower units already come with a 13 amp plug and an RCD [Residual Current Device] fitted. We do however recommend, that you remove the plug and instead, have the cabin connected directly to a fused spur. Should an RCD be already fitted to your electrical mains board, this can also be used and the RCD fitted to the unit, may be removed too.

Plumbing Details: The steam shower cabins require a 1 x hot and a 1 x cold water supply feed. The required water pipes, should be installed and fed to a position that is approximately 1 metre off the floor in the corner or central position of the room, where the cabin is to be fitted. Balanced water pressure is required above 2 bar. Should you have a Combi Boiler, you will not need a pump but you will require to have a Pressure Equalising Valve [PEV] fitted, to maintain balanced pressure to both the hot and cold supply at all times.

If your water supply uses a gravity fed system, it is recommended you fit a pump to provide the required water pressure for the shower cabin. Should the main water tank in your property, be situated above the proposed shower head position, then a Positive Head pump will suffice. In circumstances where the shower head is positioned above the main water tank, a Negative Head pump will be needed. Where a pump is being fitted, you will not require a Pressure Equalising Valve, as the pump will keep the pressure balanced on gravity fed systems.

Where an unvented hot water cylinder system like a Mega Flow is installed, these will produce sufficient balanced pressure for our showers to operate efficiently. Other types or brands of unvented hot water cylinders may vary, so it is advisable to check with the individual manufacturers or suppliers. In rare situations where the distance between the hot water cylinder and shower is extreme, i.e. cylinder on the ground floor, shower on the 5th floor, there may be a pressure issue so again, do check this with your installer or manufacturer. This information is for guidance only so in all cases, please confirm your plumbing requirements with your fitter.

We can supply a Salamander Shower Pump [Positive Head] and a Pressure Equalising Valve but do not supply other plumbing materials. The steam shower cabins are freestanding units and accordingly, we suggest that your fitter does not install the shower unit into a position where this cannot be moved away from the wall if required. The couplings on the shower cabin that connects this to your water supply, are standard 15mm compression fittings.

Also keep in mind that the shower unit is delivered in several large boxes, so please ensure you have enough space to manoeuvre these and the contents, to the installation location. Note as well, that space is required to assemble the steam shower cabin and this needs to be sufficient to allow your installer to work around the assembled shower unit, before placing in the final position.


For your peace of a direct sales company, we feel it is important when selling via the internet to make things clear and we also realise the importance of providing not only quality products at great prices, but also the need for back up, plus support for parts and customer queries too.

With the shower cabins, we are officially appointed resellers for the main UK distributors of the ranges of shower units we sell and as such, are fully able to provide Customer Support for the products and spare parts too. Our distributors also work closely with the manufacturers, to improve the products we sell and ensure they meet the standards that we and our customers expect.

Glass: All the Shower cabins we supply have tempered safety glass of between 5-6mm. The back panels of the cabins are made of mirrored tempered glass, so you do not need to tile behind the cabin.

Frames: Unless otherwise stated, the frames are made of 1.2mm aluminium, thus offering good structural support and stability. The cabins are designed to be free standing and to enable easy servicing should the need arise.

Tubs/Trays: All bases in the cabins are fitted with a fully supporting framework bonded to the tub, which affords a stable footing and assists in offering overall structural stability.

Thermostatic Valve: All steam units have thermostatic valves - this enables you to mix the water temperature to your requirements, with a safety device built in to allow water up to 38 degrees only.

Certification: CE, RoHS industries approvals. The steam generator and pump we use pass TUV approval and the pumps also pass UL approval
