Mariusz made a great job of renovating our bathroom, toilet and bedroom during 2023. His attention to detail and quality of workmanship are exceptional and we have been delighted with the results. Along the way he came up with practical and innovative solutions which all helped to deliver an outstanding result.
I would have no hesitation in recommending him for any project.

The bathroom renovation transformed my dull space into something stylish and functional. The installers were knowledgeable and completed the work to perfection. Worth every penny!

We are extremely happy with the renovations of our two bathrooms and two bedrooms thanks to our builder’s (Mariusz) care and precision when completing the work. This was our first renovation project, so we had a lot of unknowns in front of us which Mariusz kindly guided us through with his client-focused expertise.

He was very detail-oriented and had a keen eye for finding ways to maximize the space in both the bathrooms and the bedrooms. This has made a huge difference in how functional and open each room feels. The final results are fantastic, and we couldn't be happier with our beautiful, newly renovated spaces. We highly recommend him for his professionalism, skill, and commitment to the project.

Mariusz was always responsive to our questions, providing honest and realistic feedback which made the entire project run smoothly. He consistently went above and beyond, not only solving problems that came up but also proactively suggesting valuable improvements.

We found him to be both trustworthy and a genuinely great person to work with. I highly recommend him and we look forward to working with him in the future for phase 2 of our flat.

Mariuscz is a total professional, his workmanship is exquisite, the attention to detail & quality of work is of a very high standard. He is also quick, thorough & a very neat & considerate worker. Mariuscz is collaborative & knowledgeable, he changed my tired little family bathroom into a wondrous wet room, it looks & feels like high -end hotel bathroom now! He also designed & built some integrated shelves in the kitchen & made some ceiling repairs & redecorated my wooden staircase . I would 100% recommend Mariuscz, he's an absolute gem.

Over the past 12 Mariusz has renovated two of our bathrooms and a bedroom including flooring.
Initially he did our top floor bathroom including repiping and a complete reconfiguration. He created our “spa” bathroom.
Our second bathroom is the family bathroom which he has just finished. He made great suggestions for design to maximise our space. Details which I would never have considered and have made the difference between a good bathroom and a great one.
Finally he renovated one of our bedroom which included designing some bespoke fitted wardrobes and building some inbuilt shelving. Again his design suggestions made all the difference in the room.
Finally we were living in the house whilst all this work was going on and Mariusz understood we had our children at home and made sure he was considerate of this, keeping things tidied away to reduce impact on our family life.
Plans for more work with Mariusz in the near future.

Navi have carried out several bathroom and tiling works for us over the years. In 2013 they built, from scratch, a new shower room as part of an extension we were having built. They suggested a stunning tile design which we would never have come up ourselves and which gives us a Kondian “spark of joy” whenever we use it. As part of the same project they tiled a patio with large-sized Italian tiles which are particularly difficult to lay correctly. The end result was faultless.
In 2014 they refurbished a shower room in our converted attic. Their tile design in this case includes a subtle change in the colour of the floor tiles which react differently to the angle of sunlight coming into the room at various times of the day, which is very pleasing.
In 2018 they retiled and refurbished the main bathroom in our house. Again, a particularly striking design was suggested which continues to delight us. A suggestion to use an air switch for the new shower head for safety and ease of use was another innovation which has proved very practical.
In the last 4 years, after our daughter bought her first flat, major refurbishments have been necessary and work of a high standard has carried out in her kitchen and bathroom.
In all the works that have been carried out for us the quality has been excellent. All the Navi jobs have been characterised by care and politeness and have been competed on time and within budget.

Mariusz has renovated 3 bathrooms for me and I have always been very pleased with his work. He is quick, pays great attention to detail and excellent at finding solutions to tricky problems. Would highly recommend.

From late 2020 into 2021 Mariusz renovated one bathroom and built another bathroom + infrastructure from scratch. In each case, he helped with the design, and contributed creative and practical solutions which have given fab results every time, eg on hidden storage, working with marble to create a rounded edge, tips for back lighting, alcoves, flooring structure, a hidden extractor fan, what glass to use and so on. He also built cupboards and drawers from scratch in one of the bedrooms. Needless to say everything is still working like a dream. On top of that, Mariusz is kind, calm, on time and tidy - a pleasure to have around!

Mariusz helped us with a new bathroom and two separate toilet areas as well as various other home renovation projects. His work is excellent, he is courteous and friendly, always a bonus when someone is in your home. He turns up on time when he says he will and is reliable. He was very good at resolving problems that occurred and suggesting solutions along the way. We were very pleased with the end results and his craftsmanship is first class. He can do all the trades required to do a bathroom and more and this makes for a seamless result. We can thoroughly recommend him.

Mariusz has worked with my wife and I on a number of projects since 2018. These have included the creation of a new ensuite bathroom and walk-in shower and the modernisation of existing toilets and bathrooms in our house. Not only is he an excellent bathroom fitter and tiler but he always has his own suggestions on how to improve upon what we had originally planned - these are always worth consideration.
We have found Mariusz totally honest and trustworthy, very hard working and conscientious.
We have no hesitation in thoroughly recommending him for both his skill and for his integrity.
