I am trying to find interesting lights for a small guest loo, to go above a small sink on either side of a mirror. The guest loo is contemporary, decorated with black wallpaper with silver flowers, black loo and black sink on a black cupboard. Do you have any ideas. Thank you

There are many wonderful lights suitable for bathrooms. You need to confirm the type of lights which have an IP rating best suited to this situation with your electrician. Companies I suggest you try: Hector Finch and Vaughan Designs (for both of these link to Wall Lights and then Bathroom Lighting). Jim Lawrence, Fritz Fryer, Equipoise (Baulmann range), and Brilliant & Great Lights

My husband shaves in our steamy shower room and seeing his reflection in the mirror is a problem. Can you help?

Have a look at the range of bathroom accessories from Bathroom Origins, which includes this El-Kastos bevelled edge demister mirror with an IP44 rating, suitable for Zone 2 and outdoors.

Where can I buy a toilet and bidet in one?

Toto manufacture a toilet and bidet in one called the Washlet. It combines very contemporary technology with good looks; the non-stick surface allows waste to clear without having to scrub the bowl. It is available in the UK through CP Hart.

I would like a bathroom designed in book-matched marble. Who could help with the design, supply and installation?

Vitruvius has been established for many years as experts in the supply and the application of marble, granite, slate or limestone for interiors, exteriors, and bespoke works of art. Stone Age provide a huge range of stones and can help with the design, selection and installation of book-matched marble for your bathroom.

I was wondering if you could advise about how to waterproof a carpeted bathroom floor?

Wool carpet is unsuitable for bathrooms. If it persistently gets wet, the backing and underlay deteriorate.  There is no way to waterproof carpet that we are aware of, but you could use a good bath mat to absorb some of the water. Balineum  for example, have a good selection, as do Woods of Harrogate. However, it would be far better to change the flooring, even if your home is rented. Carpet can be taken up then relaid once you return your home to the landlord. Flooring that is best suited to bathrooms includes cork, vinyl, linoleum, ceramic and porcelain tiles.
