Go to Karndean website www.karndean.com. Their Looselay Longboards have the look of timber but are a cushioned vinyl plank with acoustic qualities that have been rankedinternationally by Marshall Day (check them out on google) and can be used with underfloor heating. Also have an R10 slip resistance rating.....(as a guide, R11 is what is expected behind pub bars etc), so is at the top end of the slip resistance spectrum. This is a great option on a 2nd floor and look amazing. As a flooring company in NZ, we believe this product in particular will be amazing in apartments where the kitchen areas are on an upper level, as laminate timbers can have a "hollow" noisy sound, even with noise reducing 2mm underlay. Good Luck.

Depends on the installer and what bamboo they're using.

The bathroom has now been waterproofed and the floor being screed today. There will be a small step down at the entrance to the shower area to avoid water 'falling away' from the shower and towards the door. Thanks everyone from your feedback. Much appreciated Houzzers

Hi Badobbs Structafloor will only span 600mm unsupported in the 22mm and 450mm in the 19mm version so no, it alone won't fix your issue. A simple fix would be to pull up the floor in the affected area and then 'pack' it up to level, THEN lay some structaflor over the new supported sub floor. This is done by getting a laser level and marking out the low points in the joists then making up packers to suit, or installing a packer and planing it down to suit. It depends on the level of dipping. It will be your cheapest option and definitely a job for your carpenter (unless you're handy). Regarding disturbing the floorboards that is nonsense. If there are other issues such as other sagging floorboards then you can address them at the same time, or fix them down properly with screws. I suspect that the real issue is that the wall removal did not take into account that the floor joists are usually fixed to it and they are now unsupported. If you get under there and find issues with your joists/bearers then it is not a big deal to install a couple of stumps/connect bearers to support them whilst it is open. We do it all the time. Either way laying a new floor over a subfloor without addressing it would be a waste of money and will degrade your new floor. Cheers
