Have you heard about the dumawall tile? Fully waterproof and easy to install with its tongue and groove system Quick and convenient, without drying time and joints.

Unique RCB® Patented Technology
Dumawall tiles are manufactured using the revolutionary RCB® technology. RCB® stands for Rigid Core Board. This unique and patented technology ensures that the Dumawall Plus tiles are extremely stable, water-resistant and safe. This also results in a very strong adhesion of the decor layer to the slab, preventing our decor layer from peeling. The ideal base for a shower you will enjoy for a very long time.
100% Waterproof
Dumawall Plus is fully waterproof, making it ideal for bathrooms, kitchens, and other high-moisture areas. Plus, it comes with a 10-year manufacturer's warranty, ensuring peace of mind and long-lasting performance.
Easy to Glue on Old Tiles
Dumawall Plus makes it incredibly easy to cover old tiles, providing a hassle-free and quick solution to upgrade your walls.
Easy to Cut
Dumawall Plus tiles can be cut with a utility knife, handsaw, jigsaw, and hole cutters for areas where circular cuts are required

Geoff firstly came and checked our bathroom and then allowed us to choose what we needed/wanted done in the makeover.
The work commenced on 29th July @8am and by Noon it was all gutted and shower base fitted, toilet and sink refitted ready for the walls and flooring to be done.
We weren’t expecting the guys to arrive till next day to do the floors, ceiling and walls but they called with us around 4pm and had the place finished just before 10pm. The guys never stopped and they were grateful we allowed them to continue to that late - but it did not bother us one bit.
End job was fantastic and everyone involved in the work where very sound and good craic.
GH interiors is your place for the makeover you want!!!!

GH Interiors was recommended to by my brother and sister, who had both had their bathrooms refurbished by Geoff and his team. We to wanted someone to come in and take care of everything, and after seeing the job they did for my brother and sister we wouldn't have went to anyone else! The lads were very professional and totally transformed our old out dated bathroom into a modern master piece. Everyone was very clean and tidy which we were very impressed with and nothing was ever any trouble. A first class job!.
Mr & Mrs Reid / Antrim

After much thought I decided to take the bath out and put in a walk-in shower so after some research and inviting a few different companies out to price the project, I just got a great vibe from the first meeting with Barry (the surveyor), He assured me that nothing was going to be a problem, and well, I believed him. The men who came where very pleasant and helpful, and everything was completed so quickly I would have no hesitation in recommending GH Interiors to anyone looking their bathroom refurbished, as I am over the moon with with mine.
Mr Dubios / Carrick

I can not speak highly enough of Geoff and his team, when I was told 2 days to do my whole bathroom from start to finish I couldn't believe it. Everything happened so quickly. I love my new shower and wall panels. They are some work team, as one was finishing another was in and sure enough everything was done in 2 days. I was so happy, the boys love their coffee and we had such a laugh, Charlie is a character! Such a pleasant experience, I can honestly recommend GH Interiors to anyone, a great bunch of lads.
Mrs Briggs / Ballymena

Love,love,love my new bathroom! Cannot believe the transformation, 1st class. Have to have a look every-time I walk past the bathroom door. Would highly recommend , Thank-you GH Interiors.
Mr & Mrs Jamison / Newtownabbey

I was absolutely delighted with the design and work done on our bathroom project. Geoff project managed the job to the highest level of expertise. I was worried about the hassle and mess but the boys were a tidy team. I've never had such clean workers before! I would like to thank everyone for my lovely bathroom, I cant speak highly enough of GH Interiors.
Mrs Madden / Newtownabbey

The service GH Interiors provided was first class. They were very reliable and professional. They turned up when they said they would turn up. Each step, the plumbing the panelling, all happened on time. Nothing was too big or too small for them to do for us and everything has been carried out to an exceptionally high quality. I would have no problem recommended GH Interiors to anybody.
