Marine Sanitation & Supply - 1900 N. Northlake Way - Suite # 121 - Seattle, WA 98103




  • Marine Sanitation & Supply opened it's doors in 1975 to provide ethical means for yacht sanitation needs. From working with the local Coast Guard to assist in writing of rules for boaters that made sense from the boaters point of view, to free advice to boaters on "how to" issues, as well as having the convenience of a one stop showroom.

    From Toilets, to Holding Tanks, Treatment Systems and Parts - Marine Sanitation & Supply makes sure you are up to date with the latest, most fashionable and economical sanitation options out there. We are a Dometic SeaLand master distributor for VacuFlush and stocking distributor of all the sanitation products they make. We stock and sell other brands like MasterFlush, Groco, Thetford, Tecma, Raritan and others. We have parts in stock for most brands of marine toilets, and for those toilets that you may think have seen their days.

    Our goal is to help you meet Coast Guard regulations and provide you the knowledge of such products. No one enjoys being stuck in the middle of a trip, vacation and or work day with a busted toilet, and not being up to date on your repair parts or maintenance requirements. The good old Bucket method or jumping in the drink, while it gets the job done, isn't the most flattering way to go about your 'business'.

    Marine Sanitation & Supply can provide you with all the necessities to legalize and freshen your outlook on sanitation. And we enjoy what we do. Come see us or give us a call. We know you will be pleased with your experience.

    Customer Review:

    I was the guy who came in yesterday scratching my head about the problems I was having with my head. You took the time to show me how it's all put together and what to be careful of and we discussed a few scenarios of what the problem might be. You sold me 4 Duck valves and a white seal for the piping. I also said I wasn't sure about my skills and you gave me some names to try in case I got in over my head.
    I went down to my boat last night and in a very short time had things pulled apart, and repaired. I just wanted to say Thank you and express my gratitude for your time; it paid off and even an inexperienced wrench like myself had it fixed quickly and easily thanks to your instructions. You made my day and I just wanted to let you know and to say Thank You!
    I will be back for sure! --John S

    For the record:

    I just want to say that the customer service (Help) that I received from Leah and then Tucker was terrific. They were both knowledgeable and very helpful. They were patient and understanding with me during our couple of phone calls on August 18 and 19. Two awesome people in my book.

    Short version: I'm cruising on my boat far from home, in Sitka, Alaska and need help. Our VacuFlush stopped working. Leah and Tucker helped me trouble the system via the telephone. They were patient and provided me great information. They emailed me pdf manuals. However, it was their thoughtful help that helped me fix the VacuFlush"

    I never would think that the high point of my business trip to Seattle would be at a marine sanitation store, but when we came in with some questions about replacing our boat heads, we got more than we expected. Leah was very knowledgeable about her product, as well as a enthusiastic sales person who asked all the right questions and was able to make informed recommendations we hadn't considered. What can I say, the girl really knows her ****!!!"
