Stewart and Alex are the complete professional tradesmen, which we trust to renovate our self serviced apartments in Edinburgh. Both are Friendly, tidy and reliable and their workmanship is impeccable.

We’ve just had GSA to renovate our bathroom while we’ve been away for holidays. Stewart and his team done a great job with excellent attention to detail. GSA team did everything from helping with the design to removing old bathroom suite, stripping down old tiles to rearranging the layout and fitting in the new suite. I was really surprised how quickly they’ve managed to complete the job (took only 7 days end to end) and how tidy the house was when we came back. One of the most reliable companies I’ve had opportunity to deal with. We will definitely be using GSA in a future and I would be more than happy to recommend their services to anyone requiring bathroom renovation.

So happy with the work. After several years of putting up with two botched bathrooms, we finally bit the bullet and decided to redo both of them at the same time. Lots of problems were uncovered along the way, but the team did a brilliant job of sorting everything out and both rooms were finished within 2 weeks and on budget. Quality of work and finish is excellent and everyone on the team really helpful and professional.

I would have no hesitation in recommending Stewart and Alex at GSA Bathrooms; professional and friendly, they have a great eye for detail and really take pride in their work. They explained each stage of the bathroom build and answered all our questions patiently! We have a beautiful wetroom now that we love. Stewart’s motto ” anything is possible” helped us achieve that.

We recently hired Stewart and Alex to undertake a complete overhaul of our bathroom, and we are absolutely delighted with the results. The guys helped us to refine our initial ideas, adding helpful suggestions and paying attention to the little things which are so easy to overlook but which ultimately make a big difference. Who knew that choosing just the right size of tile can make your room look so much bigger! The work itself was carried out to the highest standard, and with great attention to detail and finish. Stewart and Alex’s workmanship is exceptional, but as well as this their patience, good humour and their obvious enthusiasm for their craft made it a pleasure to have them in our home. We wouldn’t hesitate to recommend them to friends and family.

Stewart was a complete professional and him and his team have done an immaculate job of renovating my bathroom. It wasn’t an easy job, in an Edinburgh tenement with walls that needed squared, a floor that needed to be straightened which involved new joists, removal of a water tank and joinery to change the opening of the door into the hall rather than the bathroom. I had decided to convert an old sideboard into a double sink vanity, and Alex mapped out the plumbing and made a template for the stone top to be cut. Nothing was too much trouble! He made sure we were happy with the position of everything and was great at explaining the work involved. I would highly recommend!
