Dear customer,

If the flat is finished, you can do everything yourself: accept the flat. Drive from shop to shop choosing products or surfing the web. Select the equipment so that it fits together. Do not forget about traps, hoses, valves… Order, pay, arrange transport. Be in the flat when delivery arrives, in one or more batches. Probably in more batches… tiles will be delivered by one company. Bathroom furnishings are usually delivered by another company. You have to get the paints yourself. Floor panels can be ordered in one of the shops together with the installation. But in which store? If we ordered the door too late, there may be a limited selection of those readily available… Furniture and household appliances for the kitchen is another challenge… A team… as many teams as many stories.

Many other problems are on the way to our flat.

You probably know such stories from various sources. The nerves that accompany the finishing of the flat, not to mention the money that is being diverted in an uncontrolled way and sometimes you do not even know what it is spent on. Do we really have time for it? And health?


Grast&MTB offers you several packages of turnkey flat finishing. Everyone will find inspiration in the catalogues, first of all thanks to a huge selection of great bathroom tile series from the latest collections of Polish brand manufacturers. We also have the widest selection of ceramics, bathtubs, cabins and taps. Being a direct distributor of leading manufacturers since 1990, we always have access to new collections. Ordering a turnkey finishing of a developer’s flat at a company which does it every day, which will sign a contract with us and issue invoices with VAT 8%, will give a guarantee, prepare a project, deliver goods for construction, ensure that the team is by far the cheapest option. The Client’s most important task is to cooperate with us in the creation of the interior design of their dreams, signing a contract and sending payments after each stage of work to one account number. To one company. It really happens to us to do it all remotely, via e-mail or skype, when the Client lives far away or has really little time for meetings. Someone works abroad. Someone else lives somewhere in Poland and buys the first flat for a child who starts studies in the capital. Other clients are really busy employees of a corporation. Or parents of small children. These are our Clients. We also invite you to finish your flat on a turnkey basis in a short time, with a price guarantee.
