I am looking for the title of a 70's horror movie

The scenes I remember are


I think it's about about a house the people are getting killed in.
Saw the advertisements but never saw the movie



A woman in the shower the shower seals up at the top and it fills with water and she drowns.

And a woman is trapped behind in a wall and is crying and pounding to get out


Been looking for years but no one knows it .

If anyone knows this movie title you will have my eternal gratitude

Thanks

I've seen it! I'll ask my sister, she remembers the names of things.
