General Cleaning

Operation

Bristan products are made from premium materials, with  

hand polishing and electroplated finishes. 

 

Your taps or shower should be regularly cleaned with warm 

water, a mild pH-neutral liquid soap, and polished with a soft 

cloth. Any residues from soap, toiletries etc. should be rinsed 

off straight after use. 

Household bleaches and cleaners contain harsh chemicals and 

may damage the surface finish. Avoid using abrasive cloths, 

scouring pads, scrub sponges, steel wool or anything similar.  

 

Some surfaces such as nickel and pewter may be affected by 

the dye found in some cloths, so it is also important to avoid 

hanging cloths on spouts.

Choose the location for the wall outlet 

and create a 25-30mm hole in the wall. 

Ensure your shower accessories have 

enough reach from that position.  

Finish the wall surface.

To reduce the build up of lime scale and to 

ensure this shower works to its maximum 

performance we recommend this shower 

is serviced every 6-12 months depending 

on the hardness of your water.

Servicing Intervals
