Thank you for your question regarding the Delta Classic 400 - 60" x 30" Curved Bathtub and I am happy to assist you today.
The sides of the bathtub are straight and the curve does not begin on the bathtub until 3.8" from the center of the base of the apron of the unit, so it should not interfere with the baseboard, although if you have further dimensions you would like to include, we will be happy to review them further to ensure there will be no interference.
If we can assist you with anything else going forward, please do not hesitate to give us a call at 800-355-2721.
