Depends on the Westsail, they came in many forms, factory finished, bare hulls, semi-finished, etc, etc.
The only one I've had was bought to flip, it was bought as a finished hull
then the interior
was finished by the Swede shipwright who bought it. He didn't believe in showering much while living shoreside so he didn't put much thought into a adding a shower stall. Otherwise the interior
was well thought out, maybe he was planning on sailing in warmer waters? It did have 150 gallons of water tankage though.
The head was large enough though to put a shower curtain on a circular shower rail and add a shower head to the sink fixture so it could be sold.
I've only seen a couple owner finished examples so I couldn't comment on the factory models.
He did do a beautiful job on the interior though, the finish work was impressive and well laid out. Good at sea boat.
