Pilkington did indeed design the tiles used in Titanic's Turkish Bath and the example above is consistent with the pattern seen inside the wreck. The only difference are the colours used...this same pattern was used in many applications, with variations in colour schemes used to make each one unique. The colour scheme in the example above is close to, but not an exact reproduction of, the scheme that I personally observed in Titanic's Cooling Room.
When I first attempted to re-create the tiles for use in my CG model of the Cooling Room, I used a colour scheme very similar to what is shown here. It matched a 1911 artist's rendering of the room and the Shipbuilder description. However, when we actually had a look at the actual tiles inside the Titanic wreck, we found that there was less green in the scheme. At first, I attributed this to fading after years underwater, but other green tiles -- vibrant in colour -- used in the tile borders argued against this assumption. I concluded that the difference between what we assumed for Olympic and observed in Titanic can be attributed to the fact that each set of tiles were hand-painted and therefore included some variation.
The example provided above does not constitute a complete pattern; therefore, the repetition of any one tile does not produce the overall pattern. When I was building my CG Cooling Room model, I found that no one single tile could be repeated over and over again to create the overall design. As was pointed out above, the tile work was custom-made for each application. Titanic's tile work -- in both colour scheme and manner in which the tiles were cut across the pattern -- was therefore similar to, but not an exact copy of, Olympic's.
The tile pattern that can be seen in the renders from my CG model on my website represents my second attempt at capturing the correct colour scheme. It is not correct. I have yet to run a render of the CG model with the observed (re: correct) colour scheme.
