We've surveyed 3,745 people to calculate customer scores for big-name bathroom companies such as B&Q, Homebase, Ideal Standard, Roca, Soak, Victoria Plum and Wickes.
We asked questions and calculated scores and ratings for two key aspects of buying a bathroom:
Some fared better than others. The top well-known bathroom retailer gained a customer score of 80%; the poorest performer got just 58%
Meanwhile the top-scoring bathroom brand achieved an impressive 89% for its products, while the one at the bottom propped up the table with 61%.

As well as rating bathroom retailers and brands, we've put power and electric showers under the Which? spotlight.
We asked more than 3,000 Which? members about the electric or power showers that they own, using their feedback to give major shower brands, such as Mira and Triton, an overall score plus star ratings.
We also scored each brand for reliability based on how likely its showers are to experience a fault and how quickly any faults crop up (brands are penalised more severely if this happens soon after purchase).
We also put individual electric showers through their paces in the Which? lab, testing how powerful each model is and whether you could get an unpleasant surprise if someone turning a a tap on elsewhere in the house makes the water temperature rise or fall. .
In May and June 2019 we asked 3,745 Which? subscribers and members of the public about bathrooms they'd bought in the past 10 years and their experiences with the company they bought from.
This included rating retailers for the buying process, such as how knowledgeable the staff were and how good they were at dealing with problems, and the quality and durability of the bathroom itself.
For someone to be able to rate a brand's bathroom overall, they needed to have bought at least three of the following items: tap, shower, bath, toilet and shower enclosure. We also asked people to rate these individual components.
