This was purchased to compliment the 800 vanity unit in the same range for a bathroom refit (reviewed separately). The build quality is great - it's also pretty heavy because of this so make sure you use decent fixings to carry it! Some would argue that it's perhaps expensive for what it is but when you see the finished job you'll be glad you bought it. The only thing that let it down was the quality of the shelf fixings inside which were quite cheap plastic but if you're careful when setting the position you shouldn't have any further problems with it.
Like another reviewer here, I also have noticed a hum from the transformer. The top part of the cabinet that houses the transformer gets quite warm (at the cost of my electricity bill) because the transformer is permanently 'on'. Have dismantled and removed the wiring so now the shaver socket is inoperative and the hum has vanished. Will try rewiring with switch if I can find a suitable switch.
Having bought a shower caddy from this company which was excellent, I went for this cabinet. Very disappointing. The instructions were hard to follow, the door did not fit properly as it had an uneven gap on the side of the 'hinges'. (the hinges were just little pegs, not the hinges shown in the picture). When fixing the wall attachments on the back the wood split badly. Altogether a very poor and shoddy purchase.
