@Jerome Morelos I think you should give more clarity on how much you are willing to spend because bathroom remodels can vary widely in cost. I just did mine and I had quotes from $16k to $25k. I eventually opted to do it myself after watching a few videos from Jeff at Home Renovision and it cost just under $4,000 to paint, replace flooring, new tub and tile to the ceiling. I replaced the vanity and all towel and toilet paper rods added floating shelves, medicine cabinet new mirror and new lights.
If I had your bathrooms. I would consider re-glazing the tub and tile like some have suggested. I can't really tell the material of the floor but if it's waterproof, then a good cleaning should be fine. Paint the walls a light color to brighten up the room. The vanity looks like it has some water damage going on. I would contact paper right until I'm about to rent it out, then replace them. Get plywood vanities. I learned the hard way that pressed wood only looks pretty until it's touched by water. For faucets and towel rods, brushed nickel looks high end and maintains the look longer. All that wouldn't cost more than $700 (I may be off but I'm estimating about $250 for the re-glaze in each bathroom and doing the rest of the stuff myself) later on, the vanities may cost about $500-$600 each at HD
