Sounds like a job for tile. Think about what tile works with your decor...Victorian? And try to make that work. I've seen some pretty good 2X2 hexagonal tiles recently (Ann Sacks). Or some really nice stone basket weaves that would be appropriate.

What do you mean what works with my decor? At present I have a cream coloured kitchen units with an Aga oven. Work tops in kitchen are black marble. I want add in neutral colours for decor in the garden room. Colours I like are stone/neutral colours. Any suggestions. Any help would be gratefully accepted!

Your original post did not mention what finishes you were working with in the adjacent areas, so I put it back on you to tell us! I suggested tile for a garden room because of water. Neutral stone colors are limestones, travertines and some marbles. Patterns that echo Victorian architecture include Basket weaves, hexagons, windmills, herringbones and straight lays with accents like borders and trims. With your black counter tops and cream cabinets a Crema Marfil basket weave with a Nero Marquina dot would look quite nice. Most tile centers have examples of similar installations for you to look at, samples are usually available for the serious buyer to take home and view in their space. A border of the Nero Marquina in a 6X12 creates a"rug" feel to the installation and gives the opportunity to use the same material for a baseboard. i recommend a field trip to a local tile center or two. Best of luck!
