Updating the house

My husband recently replaced the faucet in our kitchen. It would leak badly every time we'd use the dishwasher. Now I've turned my attention to the bathroom. So far, everything is still working properly. However, it looks like it belongs in the late 70s. A new sink and perhaps one of the Toto toilets would help. And either a new carpet or some tiling instead. Anything would be better than what is there now.
