A luxury bathroom will be overboard on expectations, if it just provides the basic necessities with a flourish, it simply doesn't qualify as luxury. A fan or ventilation source, private commodes, spacious counters, smooth, unchipped countertops, a marble tub, amazing water pressure in the shower, high-quality toiletries, robes, and plenty of fluffy towels that you can curl up in are things that one must expect in a luxury en suite bathroom.
