Kitchen's suffer from extreme humidity variation, so you should fully adhere the solid or engineered flooring to avoid a bowing/warping floor in a few months time However, here's another viable option; luxury vinyl tiles (LVT). Generally, LVTs are 2.5mm thick, made from 100% pvc (therefore waterproof), come with a thick polyurethane wear layer that normally is backed up with a manufacturers warranty, with a wood or stone effect finish. LVTs are great with underfloor heating and unlike ceramics, they don't break when heavy objects are dropped on them and unlike wooden floors, once laid, LVTs need no further maintenance other than regular vacuuming and washing. LVTs are almost indestructible! There are many options available but us Flooring Gurus recommend going for a recognised brand. The whole idea about an LVT is for it to look authentic. They need to genuinely look like the wood or stone flooring they are mimicking. Cheap alternatives, when installed, look ... well ... awful! Try looking at Polyflor's Colonia and Camaro. We sell these products online at www.flooringmegastore.co.uk and if you made contact with us, we'd be happy to despatch a few free of charge samples to you, plus a glossy catalogue, to help you research the products a bit more.

We are in the process of filling our gaps with pine slithers (they cam in different widths) You can buy them online. You do suffer from bald/ red knees when you hammer them in and then need to chisel them down so they are flush with the rest of the floor but it really does help. What you can also order with the pine slithers is pine saw dust with resin - you mix the two up and can fill the really narrow gaps which the slithers don't fit into. If you don't mind spending the time doing this I would recommend it yourself (especially if you're worried about costs), depending how big the surface is, and then have someone in to do the sanding. The varnishing you can also do you yourself with a normal paint roller. We also recently had a quote for sanding and varnishing and I think it came to £500 for mid size living room and 3 m length hall.

I know exactly how you feel. I had a similar situation. The prospect of lifting the board and potentially raising the level made me wait. The wood darkened, and now I'm never fully sure where that board is. In fact, I forgot all about it till I saw this post. Wait a while. If it still bothers you in six months or a year maybe then consider lifting it. But I guarantee you won't, lol!

I disagree. This is standard whitewood T&G flooring. It's generally laid across joists by builders on the first floor of two storey houses as a cheap subfloor ready to take a floor finish. I've seen it sanded and varnished / stained and while it looks OK for a few months, it doesn't wear well as it's a (very) soft wood and is very noisy, particularly in the rooms under. If you want a wood finish without breaking the bank, there are some good laminates that you can lay over the T&G boards. A semi-engineered board would be better but will cost a bit more.
