Water going the wrong way when showering

I just bought a used Hanse 350 2008/9 model. It was buildt in 2008, but sold in 2009, so not sure what that makes it?

Anyway, I live in my boat and done it for 1 month now. The most annoying part is when I shower (shower is in the front of the boat) the water goes the wrong way. Will try to explain abit better :)

The whole boat seems to be abit heaver on the front, so when I shower the water goes from the back of my bathroom (where the shower and drain is) and straight to other end of the bathroom. Resulting easy 2-3 cm with water on the floor before anything goes up to the drain. This results in water sometimes on the floor in the cabin in the front and main living room. (new to boats, so please be kind)

Allso it is a pain to get the water away, had to buy a tool you use to wash windows with to try to get all the water from one side of the bathroom to the other. Beside the bathroom is small for a guy like me at 1,90cm, but taking a shower is like 20 min for me. 5-7min showering, the rest of the time cleaning the water up.

Anyone had this problem and how can I fix it?

Allso, the big steering wheel or whatever its called in english of my boat is freakin big and heard you could buy a new one you can pack together so it dont take up so much space when you aint using it?

Sorry for long post, abit tired and just had shower :)

How do you plan on doing this? Cutting up the floor and everything?

Somebody else has suggesting getting some ballast in the back of the boat, but not sure how that could work out?

Allso building the floor up so the water goes the right way, but that I think wont work due to there aint too much height to work with.

But if I was going to do this, how do I get under the floor? The whole bathroom looks like its 1 big item with very little ways to get under the walls/floor and stuff.
