Am I being ridiculous?

My fiance and I bought our home last April. It's a bit of a fixer upper. We're getting married in May. Anyways, for our wedding present my future sil said she will be buying us tiles for a bathroom floor. The catch is that she is picking them out. And deciding which bathroom to put it in. It's a great gift, don't get me wrong. But we have other plans for our bathrooms already. And we have no idea what style or color she wants to pick out. Would it be rude to ask for a gift card to pick it out ourselves instead?

Mil also wants us to spend our honeymoon working on our house, but That's a whole different story. Lol
