There is no hard rule about what a luxury bathroom comprises of, although they all have one thing in common: a feeling of undeniable grandness, where every detail is carefully considered to create a consistent look of luxury. Traditional suites like iflo's Cascada design invoke this feeling, pairing classic features like pedestal basins with a high-standard modern build quality to create an impression of grandeur. You don't have to just stick to traditional styles for a luxurious bathroom however. The contemporary styling of suites such as iflo's Trapini, can be paired with a spa-like colour scheme for modern-inspired luxury.
Stylish bathrooms require a delicate balance of innovation and restraint: they create a look of sleek, chic modernity, but shouldn't go over the top with garish colour schemes or unnecessary gimmicks. Careful planning is paramount. Every element should be a functional, useful addition that matches seamlessly with the rest of your bathroom. Because functionality is such an important aspect, minimalistic designs that place the emphasis on usability are common in stylish bathrooms. For example, iflo's Rhea suite includes a wall-mounted WC - these save valuable floor space, but also draw the eye thanks to their striking angular styling.
You can include elements of both luxury and style in your bathroom, so long as they combine tastefully to create a cohesive overall feeling that you are hoping to achieve. You might decide that a stylish geometric suite pairs well with the luxurious dark marbled tile pattern you're keen to sample in your space. There's no reason why you can't have both, although getting a second opinion from a bathroom specialist is advisable if you're new to the process of home renovation.
