Well IMO, the strong effort to make ships as luxurious and as comfortable as possible was just beginning to get off the ground. When you ask most people about how they think First-Class on the Titanic was, they would say that every wall was covered in expensive, ornate wood, everywhere there was only the finest carpet and fabrics used, every room was bristling with crystal chandeliers, and everything was either gold plated or buried in marble. Of course if they do some decent research, most people find out for the most part that this was not the fact (at least cabin-wise). Only about 39 First-Class Suites on the Titanic somewhat matched this exaggerated description. I think that White Star thought that most people wouldn't sit around cooped up in their staterooms for the entire voyage enjoying this luxury; they would be out walking around on deck enjoying the fresh air, playing cards or writing in the public rooms, exploring the ship, etc, so they put a big effort into making their public rooms the finest on the sea; only later would the attention turn to cabins.
Of course back in 1912 on a ship, even the average First-Class cabin on the Titanic would have been considered more than comfortable. After all, brass bedsteads, wicker armchairs, horsehair sofas, electric heaters, ceiling fans, and marble washstands would hardly be roughing it.
