    You’ll need building regs for things like insulation, drainage, ventilation and electrics. As for the costs, it can vary depending on the condition of the garage, the quality of the bathroom fittings, and whether you need new plumbing or structural work.

    Planning not necessarily needed but the main thing with Ensuite is the foul water drainage location which could affect the price drastically, hot and cold not a problem as the deliverd under pressure, and worst case scenario for foul where gravity isn’t possible then a saniflo pumped system would have to be utilised , id allow anywhere from 10 to 15k minimum, again also depending on the bathroom specifications
