Red ironbark (The true red heartwood) matches near perfect. Failing that, bloodwood is a near match.

Your tile will co-ordinate beautifully with the timber if you can pick one of the darker colours out of the timber and select a tile in this family of colour. The trick to making a colour concept work is to either co-ordinate or contrast. If your timber is as busy with grain and colour as the image you've shown, then maybe co-coordinating is the best way to go. Never chose materials independently of each other - always take a tile sample home to see in the natural light, next to the timber. I hope it all works out the way you envisage it. Cheers, Michelle

Very unclear. It could be an epoxy or polished concrete...hard to tell from the photos.

I agree, it looks like Blackbutt tongue and groove timber, like I had in a house I once owned. Blackbutt is one of the hardest wearing timbers. The photo shows how it looked when the house was on the market for sale. It had not been re-sanded or re-polished since it was built 16 years prior. It still looked as good as new. The timber looks lighter than in your photo as all the lights were on when my photo was taken. If your house was built earlier, it could be one of the gum species, eg spotted gum.
