Design, supply and installation of bathrooms

TOPMARKS are bathroom experts.  We design, supply and install bathrooms and do it very well.  We probably know – almost – everything there is to know about bathrooms, wetrooms and shower rooms in London houses and flats.  This means you get true experts fitting your next bathroom.

TOPMARKS design and install bathrooms from top to bottom.  From the water and waste pipes concealed below floors and inside walls to the tiles, taps, showers, baths, heating, lighting and many extras. We know what makes a bathroom feel comfortable, relaxing and even luxurious.  You also get a comprehensive and valuable “no quibble” guarantee.  So you get peace of mind when we design, supply and install your bathroom.

Ask us a question…test us…

Many clients start by coming into our showroom to ask if we know how to resolve difficult problems.  Why is their shower leaking? And why does the bath empty slowly or the toilet get blocked?  Why is their bath no longer shiney?  Do we know how to increase water pressure and create a powerful shower? And do we know how to make recessed shelves in bathrooms?  Many clients also report cracked tiles and ask if we know how how to stop it happening again? And do we know how to stop that horrible black mold growing on the grout?

Of course we know.  This is our daily bread-and-butter work.  For us, designing a bathroom means not just drawing an attractive plan. It means making a bathroom that resolves all problems, does not leak and actually works properly for you, our valued client.

Your new bathroom must look good and work well

It must endure for many years

It must be fully guaranteed


Answer: years of practice in bathroom design and fitting and the relentless pursuit of perfection

The company’s staff have been working together for over 17 years in London.  We started off with knowledge and experience but that has grown substantially over the ensuing years, aided by a shared desire to do every job as well as possible. To solve any problem thrown at us.  Never to give up in the face of adversity.  Every bathroom in London homes ranging from modern concrete-framed apartment blocks to Edwardian, Victorian or earlier houses brings a fresh challenge and a problem to solve.  We are successful because we find solutions and produce attractive finishes to our bathrooms.


General Builders

We are good, old-fashioned General Builders.   That means we can re-model or make changes in your home. Knock down supporting walls, make extensions and loft conversions, fit wooden and stone floors, make new ceilings and walls.  We make cupboards and other furniture for bedrooms and receptions rooms.  We make new staircases.  We do all electrical and lighting work, heating, gas boilers and central heating.  We re-tile roofs and we carry out a full range of structural repairs including the use of helibars (and if you know what they are, it probably means you need them and require our services!). It is because we are so well-rounded in our knowledge and experience that we excel at bathrooms – good bathrooms generally being the most difficult and demanding of all jobs.


TOPMARKS began fitting Ikea kitchens many years ago before designing and fitting kitchens made in Italy and more recently in Germany.  However with recent changes in exchange rates, English-made kitchens manufactured to the same quality as German ones are now substantially more economic.  We  use all our experience and work with English manufacturers to design and deliver a wide range of kitchens at very affordable prices!

Whether you are seeking a traditional wooden kitchen, Shaker, painted, melamine or lacquered, you will be pleasantly surprised to find our prices are lower than might be expected.  We have worked hard to get the price down while maintaining quality.  We now have a very good offer for anybody wanting a new kitchen in London.  Come into the showroom for a discussion and we will try to make you happy with the lowest price possible for a new kitchen.
